Initial stage—the first 1–9 weeks, in which are the greatest number of deaths, with 90% due to thermal injury and/or blast effects and 10% due to super-lethal radiation exposure. Intermediate stage—from 10 to 12 weeks. The deaths in this period are from ionizing radiation in the median lethal range - LD50; Late period—lasting from 13 to ...
The field strength of electromagnetic radiation is measured in volts per meter (V/m). [2] The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [3] [4]
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.
Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. It can be either detrimental or beneficial for materials.
Despite the lethal radiation and blast zone extending well past her position at Hiroshima, [48] Takakura survived the effects of a 16 kt atomic bomb at a distance of 300 metres (980 ft) from the hypocenter, with only minor injuries, due mainly to her position in the lobby of the Bank of Japan, a reinforced concrete building, at the time.
Patients receiving treatment for prostate cancer and cancer of the cervix receive lethal doses of radiation.

Radiation is not always dangerous, and not all types of radiation are equally dangerous, contrary to several common medical myths. [11] [12] [13] ...
The Chernobyl disaster in 1986 exposed to radiation about 125,000 mi 2 (320,000 km 2) of land across Ukraine, Belarus, and Russia. [155] The amount of focused radiation caused severe damage to plant reproduction: most plants could not reproduce for at least three years.
