Controversies about Radon and Radioactivity - Part 2
From 1944 until 1974, the federal government funded radiation experiments on humans. In 1994, President Clinton appointed the Advisory Committee on Human Radiation Experiments. It reviewed 4,000 recorded human radiation experiments and hundreds of intentional radiation releases, which involved tens of thousands of unsuspecting subjects. A stack of copies of the "Nuremberg Code of Medical Ethics," which prohibits medical experimentation on people without their consent, was found in Defense Department files, all stamped "top secret."
Experiments were conducted on children, seriously ill and sometimes comatose patients, African-Americans, and prisoners. The poor were appropriate subjects because, as a professor at Emory University explained, "We felt we had a right to get some return from them, since it wouldn't be in professional fees and since our taxes were paying their hospital bills."
Since the very beginning of the Manhattan Project people were injected with plutonium or uranium. Total body irradiation experiments at the University of Cincinnati recorded eight deaths. Radiation doses were given to fetuses and hundreds of women at the Vanderbilt University. Prisoners' testicles were irradiated in Washington state and Oregon. Orphans at a school in Boston were fed plutonium-laced milk. Johns Hopkins University invented the radium nasal irradiation procedure given to schoolchildren nationwide and to military personnel. At a state school in Massachusetts, institutionalized mentally retarded children were lured into experiments by special treats like extra milk, occasional outings, and membership in a "Science Club."
On many occasions between 1944 and 1968, radiation was deliberately released mostly from nuclear weapons complexes to observe the impact on the population and environment. In the infamous 1949 "Green Run" release, a huge cloud of radioactive gas was secretly discharged from the Hanford site in Washington state.
Hundreds of uranium miners died unnecessarily of lung cancer. The Atomic Energy Commission deliberately did not advise them on the dangers of radon and proper mine ventilation systems were not installed, but data on their health were secretly collected.

(Disclaimer: Not just another excuse to avoid the “big commitment.”)
In the early 1980s, the New York State Health Department discovered that some gold jewelry was radioactive. The likely source of the radioactive gold was a state-owned institute for cancer research. News accounts reported that at least 14 people developed finger cancer and some had suffered finger or partial hand amputations from wearing the radioactive rings.
On a much larger scale, The Washington Post reported in 1999 that radioactive gold recovered from dismantled nuclear warheads made its way into the jewelry industry. The gold and other metals were stripped away from the circuitry and plating of the warheads and smelted at Paducah Gaseous Diffusion Plant in Kentucky since the 1950s.
A worker found radioactive gold flakes in an old mold used to make gold ingots. The flakes were found to emit radiation at an alarming rate of 500 milirems an hour. In comparison, the average person receives about 250 milirem of radiation per year from all sources, including radon, X-rays, and cosmic radiation.
Gold jewelry made out of such contaminated gold would give the wearer twice as much radiation each hour as most people receive in a year.
Ex-employees, who later sued the plant over exposure to plutonium, claimed that the gold bars were not checked for radiation prior to their release.
Although the recycling of gold at Paducah was a secret, it became public in 1980 when one of the gold bars was stolen by an employee and sold to a jewelry store.
Department of Energy confirmed that gold was recovered from dissembled nuclear weapons at Paducah since the 1950s but stated that it was not contaminated with radioactive material.
Two years later, DOE clarified that millions of pounds of radioactive metals were released into the stream of commerce from the Paducah plant, but the radiation levels were so low that they were unlikely to pose health risks. This included between 2,800 and 5,300 pounds of gold shipped to the U.S. Treasury and some commercial facilities. DOE stated that the potential exposure to the public was less than one-tenth of annual natural background radiation levels.

Irradiation of people blossomed into big business for Johns Hopkins University in Baltimore since its humble beginnings in 1912. Hopkins then decided to participate in the emerging radioactivity craze and sent one of their experts to Vienna to purchase 200 milligrams of radium. He carried it for a few hours in a lead wrapping in his pocket, but soon developed nausea and skin burns that took weeks to heal. In the 1930s, Hopkins devised an applicator with a capsule containing radon gas that could be inserted into the nose to irradiate and shrink adenoids and cure deafness.
The bid break came during World War II. Before the advent of pressurized planes, about one third of Air Force pilots was grounded by temporary deafness caused by air pressure changes during flight. Submariners and divers had similar problems. Hopkins claimed it had the cure and obtained a contract from the government to set up irradiation programs at military bases. Long-lasting radium replaced radon in the applicators and tens of thousands of servicemen were treated over the next 20 years. At least 5,000 submariners were treated in Groton, CT, and many thousands of civilians after the physician set up lucrative private practice in New London, CT.
From the '40s to the '60s, up to 2.6 million American children were treated with Nasal Radium Irradiation, a procedure promoted by Johns Hopkins, for enlarged adenoids or tonsils and mundane problems, such as head colds, stuffy noses, sore throats, and ear infections. The radioactive doses to children were 2,000-13,000 rad to nasopharynx, 100 rad to thyroid, 50-100 rad to the pituitary gland, and 15-40 rad to the brain. This "amazing" treatment reportedly helped children blossom into higher grades, improved their self-esteem, and even their looks.
Although radiation was proven harmful already in 1940s, Hopkins still claimed in 1960: "These treatments have now been given for more than a quarter of a century to hundreds of thousands of patients and no instance of damage from irradiation has yet been reported."
Decades later, tumors, thyroid and immune disorders, brittle teeth, reproductive problems and various bizarre diseases started to appear. The government appointed an Advisory Committee on Human Radiation Experiments, chaired by a professor of bioethics at Johns Hopkins. It decided to provide screening and health care to Veterans who received NRI. But, although the cancer risk to treated schoolchildren is ten times higher, it declined even to notify civilian patients. Johns Hopkins and the government have never admitted any liability.

Federal government does little for suffering civilians
Smokers who call intolerant non-smokers "Nazis" are not entirely wrong. Adolf Hitler, just like Mussolini and Franco, was a non-smoker and personally directed anti-smoking campaigns.
German scientists recognized already in 1930's, decades ahead of others, that smoking causes lung cancer. Nazis founded the "National Socialist Institute for the Study of the Dangers of Tobacco" with the mission to protect the mankind against one of its most dangerous poisons. Smoking was branded as socially undesirable and was forbidden in many public places. Tobacco advertising was strictly regulated and athletically or sexually oriented cigarette advertising was prohibited. Smokers, who frequently missed work due to sickness, were forced into nicotine withdrawal clinics. Western agents sent to Nazi Germany had to first sand off tobacco stains from their fingers to avoid detection.
Decades ahead of modern Western governments, the Nazi government pursued public health policies and declared a "War on Cancer." Nazi propaganda promoted health as everybody's primary goal and responsibility.
They carried out massive campaigns for early detection of cancer. Women were shown how to examine their breasts for cancer, and men were advised to have their prostate examined as frequently as they check their car engines. The Nazis waged a large-scale anti-smoking campaign.
German scientists recognized that radon causes lung cancer and reduced the radon exposure to miners by proper ventilation. They were also the first to recognize that asbestos causes lung cancer and that asbestosis is an occupational disease. The Nazis invented occupational health and safety. They placed thousands of physicians in factories to monitor the health and safety of German workers.
The Nazis were promoting healthy nutrition: whole-grain bread (baker shops were forced to produce it by law), fruits, vegetables, and less meat. Soy beans became politically correct and earned the nickname "Nazi beans." They established the mineral water market in Europe.
Hitler was a vegetarian who called meat soup "cadaver tea." He was fond of pure olive oil and worried that consumption of whale oils would endanger the world's whale population. Himmler was strictly against the use of refined flour, sugar and white bread. Rudolf Hess preferred nutritional whole-wheat biscuits and carried his own vegetarian food even when invited for dinner, a habit which annoyed Hitler.
Hess strongly believed in homeopathy and was an advocate of natural healing. Alternative medicine and organic therapies were promoted. A government commission was established to evaluate home therapies as the cure for cancer. Large tracts of land were used for cultivation of herbs and healing plants. The Dachau concentration camp became one of the leading producers of natural herbs and spices in the world, and it also produced large quantities of organic honey.
The Nazimedizin is infamous for terrible experiments on concentration camp prisoners. But in the promotion of public health, prevention of diseases and fighting cancer the Nazis were decades ahead of their time.
"The Nazi War on Cancer" by Robert N. Proktor
Marie Sklodowska Curie was the first woman scientists to win worldwide fame and one of only four persons to have won two Nobel Prizes. In 1903, she shared the Nobel Prize for Physics with her husband Pierre and with Henri Becquerel for investigation of radioactivity, and in 1911 she received the Nobel Prize for Chemistry for her discovery of two new elements - polonium and radium. Later on, Curie's daughter Irene and her son-in-law Frederic Joliot-Curie also won Nobel Prizes, as did her neighbor and a close friend Perrin.
Wilhem Roentgen discovered x-rays in 1895 and frightened his wife with an image of her hand bones complete with a wedding ring. He refused to take out a patent for the benefit of mankind, and at the time of his death was nearly bankrupt. Inspired by Roentgen, Henri Becquerel discovered in 1896 that uranium emits mysterious radiation captured by photographic plates and makes surrounding air conduct electricity. Couple years later, Marie Curie persuaded her husband to abandon his research (he discovered piezoelectricity) and join her in exploring this mystery.
The Curies tested various materials for radioactivity. They found that pitchblende, then a worthless ore residue from the uranium producing plant in Joachimsthal (now in the Czech Republic), induced a current in air 300 times stronger than pure uranium. The Curies reasoned that there must be another very active element in the pitchblende. They called it polonium after Marie's native Poland, and coined the term "radio-active." Later that year, one year after their first child was born, they detected trace amounts of an element two million times more radioactive than uranium - radium. After backbreaking manual labor on chemically refining the pitchblende, the Curies managed to separate the new elements polonium and radium. During four years, they refined eight tons of ore to produce one gram of radium. The Curies presented a spec of radium, at that time more precious than diamonds, to their good friend Becquerel. He carried it in his vest pocket until he found it gave him skin burns.
Pierre Curie was killed by a horse-drawn wagon in 1906, but by that time he was already limping from bone deterioration. Marie continued the research of radioactivity. She devoted much of her life to promoting radiation as a cure for cancer. In her honor the unit of radioactivity generated by 1 gram of radium was named "Curie." As a gift for her scientific discoveries, Marie was presented with a pendant of radium. Madame Curie died in 1934 of leukemia, a cancer now known to be caused by radioactivity. Although her body was covered with lesions, she denied to the end that her beloved radium has killed her.
Years after Madame Curie's death, photographic films were placed between the sheets of her laboratory books. The photographs showed numerous fingerprints caused by the radioactivity on her hands. Her daughter Irene Joliot-Curie, who became only the second woman to win a Nobel science prize, later also died of leukemia caused by exposure to radioactivity, while her husband met the same fate a couple of years late after calling it "our occupational disease."

1993 An "alarming" suicide rate among soldiers and engineers who helped clean up the Chernobyl nuclear disaster is the result of radiated nervous systems, the breakdown of immune defenses and stress. The San Francisco Examiner reports that nearly seven years after the world's most serious nuclear reactor accident exposed about 500,000 Ukraine residents, reactor workers and cleanup crews to radiation, the death toll stands at 7,000 - of whom 18 percent have taken their own lives, according to statistics provided by the Russian government. Thousands more are suffering from symptoms caused by excessive radiation, says the article. More than 40 percent of all former Chernobyl workers who ask for medical assistance suffer from severe after-effects, such as permanent memory loss and impaired thinking ability.
1993 In a new report, the Russian Federation details how the USSR broke the international rules for thirty years by dumping radioactive waste in the oceans. The amount of radioactive waste includes 2.5 million Curies and 18 nuclear reactors from submarines and an icebreaker. These were mostly dumped in the Kara Sea.
1993 Russia dumps liquid radioactive waste into the Sea of Japan.
1993 French deliberately cause a meltdown under almost identical conditions as at Three Mile Island in the Phebus reactor in the south of France. Close circuit televisions show a bright blue glow as the fuel rods melt. Environmentalists criticize the experiment as dangerous and unnecessary.
1994 Russian scientists disclose pumping 3 billion Curies of radioactive waste under layers of shale and clay for the last 30 years at sites at Dimitrovgrad (near the Volga River), Tomsk (near the Ob River), and Krasnoyarsk (on the Yenisei River).
1995 Russians drinking water from the Techa River (draining from the Mayak plutonium facility near Chelyabinsk) have more lymphatic genetic mutations (T-cell antigen receptors) than people who suffered radiation from atomic bombing of Hiroshima, according to Japanese and Russian scientists. The region's death rate is higher than its birth rate. The Japanese scientists are from the Radiation Effects Research Foundation in Hiroshima. An international symposium on radiation effects on human health is held in Chelyabinsk to discuss the hazards posed by the Mayak plant to nearby residents.
1995 Artificial reservoirs for liquid nuclear waste in Russia's Ural region may overflow if left unrepaired, destroying nearby areas around Chelyabinsk with what is called a "nuclear flash flood," Russian officials warn. The reservoirs at the Mayak chemical plant now hold a total of 400 million cubic meters of liquid nuclear waste, and there is a strong possibility the embankment will give way, inundating towns and villages along the Techa River nearby. No effective measures have been taken to prevent a 33-feet-high flood with a radioactivity as high as 200,000 Curies of Strontium-90 and Cesium-137. Suspension of an atomic power plant project in the region has added to the danger of a nuclear flash flood, since the project was designed to accelerate evaporation of water in the reservoirs by using surplus heat from the power plant.
