How many Roentgen is safe?
Just so, how much Roentgen is dangerous?
To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite risk of cancer and other diseases.
Furthermore, how many Roentgen did Chernobyl have? 15,000 roentgen
Likewise, how many Sieverts are in a Roentgen?
|1 curie||=||3.7 x 1010 disintegrations per second|
|1 rem||=||0.01 sievert (Sv)|
|1 roentgen (R)||=||0.000258 coulomb/ kilogram (C/kg)|
|1 megabecquerel (MBq)||=||0.027 millicuries (mCi)|
|1 gray (Gy)||=||100 rad|
How many rads is safe?
Health effects A dose of 100 to 200 rad delivered to the entire body in less than a day may cause acute radiation syndrome (ARS), but is usually not fatal. Doses of 200 to 1,000 rad delivered in a few hours will cause serious illness with poor outlook at the upper end of the range.
