The women also experienced suppression of menstruation and sterility. [4] Although there were claims that the above conditions were caused by X rays the women received to investigate their health problems, the amount of radiation absorbed would be inconsequential compared to the amount they were exposed to daily at radium dial factories.
The committed dose is not intended as a measure for deterministic effects, such as radiation sickness, which are defined as the severity of a health effect which is certain to happen. The radiation risk proposed by the International Commission on Radiological Protection (ICRP) predicts that an effective dose of one sievert carries a 5.5% chance ...
Alpha radiation has a very short range in tissues compared to beta or gamma radiation: around 2–10 cells. This reduces damage to surrounding healthy tissues, producing an even more localized effect than the beta-emitter strontium-89, also used to treat bone cancer. [17] Taking account of its preferential uptake by bone and the alpha particles ...
Comparison of laboratory experiments over the last century, studies of the Oklo natural nuclear reactor (which exemplified the effects of thermal neutrons on nuclear decay), and astrophysical observations of the luminosity decays of distant supernovae (which occurred far away so the light has taken a great deal of time to reach us), for example ...
Beta particle (β) emitters such as yttrium-90 can travel considerable distances beyond the immediate tissue before depositing their energy, while alpha particles deposit their energy in 70–100 μm long tracks. [6] Alpha particles are more likely than other types of radiation to cause double-strand breaks to DNA molecules, which is one of ...

Natural background radiation comes from five primary sources: cosmic radiation, solar radiation, external terrestrial sources, radiation in the human body, and radon. The background rate for natural radiation varies considerably with location, being as low as 1.5 mSv/a (1.5 mSv per year) in some areas and over 100 mSv/a in others.
Recently, the 70-year-old opened up about the toll working those days has put on his body, especially given that he's endured multiple health issues over the years.
