Radium Jaw
Radium jaw, or radium necrosis, is a historic occupational disease brought on by the ingestion and subsequent absorption of radium into the bones of radium dial painters. It also affected those consuming radium-laden patent medicines. The symptoms are necrosis of the mandible (lower jawbone) and the maxilla (upper jaw), constant bleeding of the gums, and (usually) after some time, severe distortion due to bone tumors and porosity of the lower jaw. The condition is similar to phossy jaw, an osteoporotic and osteonecrotic illness of matchgirls, brought on by phosphorus ingestion and absorption. The first written reference to the disease was by a dentist, Dr. Theodor Blum, in 1924, who described an unusual mandibular osteomyelitis in a dial painter, naming it "radium jaw". The disease was determined by pathologist Dr. H.S. Martland in 1924 to be symptomatic of radium paint ingestion, after many female workers from various radium paint companies reported similar dental and mandibul ...

Occupational Disease
An occupational disease is any chronic ailment that occurs as a result of work or occupational activity. It is an aspect of occupational safety and health. An occupational disease is typically identified when it is shown that it is more prevalent in a given body of workers than in the general population, or in other worker populations. The first such disease to be recognised, squamous-cell carcinoma of the scrotum, was identified in chimney sweep boys by Sir Percival Pott in 1775. Occupational hazards that are of a traumatic nature (such as falls by roofers) are not considered to be occupational diseases. Under the law of workers' compensation in many jurisdictions, there is a presumption that specific disease are caused by the worker being in the work environment and the burden is on the employer or insurer to show that the disease came about from another cause. Diseases compensated by national workers compensation authorities are often termed occupational diseases. However, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osteomyelitis
Osteomyelitis (OM) is an infection of bone. Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. The long bones of the arms and legs are most commonly involved in children e.g. the femur and humerus, while the feet, spine, and hips are most commonly involved in adults. The cause is usually a bacterial infection, but rarely can be a fungal infection. It may occur by spread from the blood or from surrounding tissue. Risks for developing osteomyelitis include diabetes, intravenous drug use, prior removal of the spleen, and trauma to the area. Diagnosis is typically suspected based on symptoms and basic laboratory tests as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).This is because plain radiographs are unremarkable in the first few days following acute infection. Diagnosis is further confirmed by blood tests, medical imaging, or bone biopsy. Treatment of bacterial osteomyelitis often involves both antimicrobials and sur ...

Radium Dials
Radium is a chemical element with the Symbol (chemistry), symbol Ra and atomic number 88. It is the sixth element in alkaline earth metal, group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovery of the chemical elements, discovered by Marie Curie, Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radium Dial Company
The Radium Dial Company was one of a few now defunct United States companies, along with the United States Radium Corporation, involved in the painting of clocks, watches and other instrument dials using radioluminescent paint containing radium. The resulting dials are now collectively known as radium dials. The luminous paint used on the dials contained a mixture of phosphor and radium, a product that the Radium Dial Company named ''Luna''. However, unlike the US Radium Corporation, Radium Dial Company was specifically set up to only paint dials, and no other radium processing took place at the premises. History The Radium Dial Company was started in 1917 and was in full production of painted dials by 1918. The company was a division of the Standard Chemical Company based in the Marshall Field Annex building in Chicago. In 1920 the company relocated to Peru, Illinois to closer proximity to the clock manufacturer and major customer, Westclox. By 1922 the company had moved t ...

Radioactive Quackery
Radioactive quackery is quackery that improperly promotes radioactivity as a therapy for illnesses. Unlike radiotherapy, which is the scientifically sound use of radiation for the destruction of cells (usually cancer cells), quackery pseudo-scientifically promotes involving radioactive substances as a method of healing for cells and tissues. It was most popular during the early 20th century, after the discovery in 1896 of radioactive decay. The practice has widely declined, but is still actively practised by some. Notable examples * Radithor, a solution of radium salts, which was claimed by its developer William J. A. Bailey to have curative properties. Industrialist Eben Byers died in 1932 from ingesting it in large quantities throughout 1927–1930. * One German brand of toothpaste from prior to the Second World War, Doramad Radioactive Toothpaste, contained small amounts of thorium that was a byproduct in the manufacture of gas lamp mantles. The advertising for this toot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radithor
Radithor was a patent medicine that is a well-known example of radioactive quackery and specifically of excessively broad and pseudoscientific application of the principle of radiation hormesis. It consisted of triple distilled water containing at a minimum each of the radium 226 and 228 isotopes. The time of Radithor and radioactive elixirs ended in 1932, with the premature death of one of its most fervent users, Eben Byers, an American industrialist. This history has led to the strengthening of regulatory control of pharmaceutical and radioactive products. History Radithor was manufactured from 1918 to 1928 by the Bailey Radium Laboratories, Inc., of East Orange, New Jersey. The owner of the company and head of the laboratories was listed as William J. A. Bailey, a dropout from Harvard College, who was not a medical doctor. It was advertised as "A Cure for the Living Dead" as well as "Perpetual Sunshine". The expensive product was claimed to cure impotence, among other ills. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eben Byers
Ebenezer McBurney Byers (April 12, 1880 – March 31, 1932) was a wealthy American socialite, sportsman, and industrialist. He won the 1906 U.S. Amateur in golf. He earned notoriety in the early 1930s when he died from multiple radiation-induced cancers after consuming Radithor, a popular patent medicine made from radium dissolved in water. Biography The son of industrialist Alexander Byers, Eben Byers was educated at St. Paul's School and Yale College, where he earned a reputation as a sportsman. He was the U.S. Amateur golf champion of 1906, after finishing runner-up in 1902 and 1903. Byers eventually became the chairman of the Girard Iron Company, which had been created by his father. In 1927, Byers injured his arm falling from a railway sleeping berth. For the persistent pain, a doctor suggested he take Radithor, a patent medicine manufactured by William J. A. Bailey. Bailey was a Harvard University dropout who falsely claimed to be a doctor of medicine and had become r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radium Girls
The Radium Girls were female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint. The incidents occurred at three different factories: one in Orange, New Jersey, beginning around 1917; one in Ottawa, Illinois, beginning in the early 1920s; and a third facility in Waterbury, Connecticut, also in the 1920s. After being told that the paint was harmless, the women in each facility ingested deadly amounts of radium after being instructed to "point" their brushes on their lips in order to give them a fine tip; some also painted their fingernails, face and teeth with the glowing substance. The women were instructed to point their brushes in this way because using rags or a water rinse caused them to use more time and material, as the paint was made from powdered radium, gum arabic and water. Five of the women in New Jersey challenged their employer in a case over the right of individual workers who contract occupational diseases to sue ...

United States Radium Corporation
- The United States Radium Corporation was a company, most notorious for its operations between the years 1917 to 1926 in Orange, New Jersey, in the United States that led to stronger worker protection laws. After initial success in developing a glow-in-the-dark radioactive paint, the company was subject to several lawsuits in the late 1920s in the wake of severe illnesses and deaths of workers (the Radium Girls) who had ingested radioactive material. The workers had been told that the paint was harmless. During World War I and World War II, the company produced luminous watches and gauges for the United States Army for use by soldiers. U.S. Radium workers, especially women who painted the dials of watches and other instruments with luminous paint, suffered serious radioactive contamination. Lawyer Edward Markley was in charge of defending the company in these cases. History The company was founded in 1914 in New York City, by Dr. Sabin Arnold von Sochocky and Dr. George S. Willi ...

Harrison Stanford Martland
Harrison Stanford Martland (September 10, 1883 – May 1, 1954) was an American pathologist who identified radium as the cause of cancer and death among watch dial painters, and also coined the term ''punch drunk'' to describe chronic head injuries from boxing. Early life and education Martland was born in Newark, New Jersey. In 1901 he received a BS degree from Western Maryland College and in 1905 he received his MD degree from Columbia University College of Physicians and Surgeons. Career Martland accepted the appointment of the first full-time paid pathologist at the Newark City Hospital in January 1909. When World War I broke out, Martland joined the Bellevue Hospital Unit and as a lieutenant colonel he took charge of a hospital in Vichy, France. He later was awarded a Citation for Exceptionally Meritorious and Conspicuous Service by General John Pershing. In June 1925, Martland was chosen to fill the post of Essex County Physician. He set out to establish the medical examine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
