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.
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 ...
Thomson deliberately exposed a finger to an X-ray tube over a period of time and suffered pain, swelling, and blistering. [16] Other effects, including ultraviolet rays and ozone, were sometimes blamed for the damage, [17] and many physicians still claimed that there were no effects from X-ray exposure at all. [16]
Alpha radiation is dangerous when alpha-emitting radioisotopes are inhaled or ingested (breathed or swallowed). This brings the radioisotope close enough to sensitive live tissue for the alpha radiation to damage cells. Per unit of energy, alpha particles are at least 20 times more effective at cell-damage than gamma rays and X-rays.
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. [5] They are generally produced in the process of alpha decay but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet, α.
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 ...
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.
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.
