To put into context how lethal that is, a fatal dose of radiation is estimated at around 400 rem (rem, or roentgen equivalent man, is a measure of the health effect of low levels of ionizing radiation on the human body). A total of 400 rem would be absorbed by anyone whose body is exposed to a field of 400 roentgen for 60 minutes.
