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.
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1] Symptoms can start within an hour of exposure, and can last for several months.
The total energy radiated in one day is about 8 MJ, or 2000 kcal (food calories). Basal metabolic rate for a 40-year-old male is about 35 kcal/(m 2 ·h), [37] which is equivalent to 1700 kcal per day, assuming the same 2 m 2 area. However, the mean metabolic rate of sedentary adults is about 50% to 70% greater than their basal rate. [38]
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 ...
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 different ways. Alpha particles are named after the first letter in the Greek alphabet, α.
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation.
Upon analysis, scientists found that participants who stayed on standard statin treatment for their lifetime increased their quality-adjusted life years by 0.24-0.70, and those on higher-intensity ...
Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.
