Summary prepared by Lauren Griffin for discussion on 10/03/17:
Article 1: Is a Little Dose of Radiation So Bad?
The linear no-threshold model (LNT) holds that any amount of radiation increases cancer risk, with the danger rising with the dosage. The tolerance dose model claims that radiation below a certain level is not harmful. The disputed range involves annual radiation exposures below 10,000 millirems. Each side of the argument has its own data but occasionally point to the same information to support the different arguments.
Article 2: A Radiation Reality Check
Radiation comes from everything: food, the earth, living creatures and man-made objects. The average American gets 620 millirems of radiation each year with half due to background radiation. That number needs to reach 100,000 to be a threat. During the Cold War, nuclear testing on American soil caused more harm to Americans than Soviet weapons. Remember harm comes from dosage, not the particular atom. For example, Chernobyl spread a cloud 400 times the size of Hiroshima killed only 75 people. In a study of Hiroshima and Nagasaki survivors, only 1% had cancer due to radiation and there was not increase in inherited mutations. The same 1% was seen in the Fukushima disaster.
