How many Roentgen is safe?

The International X-ray and Radium Protection Committee, now known as the International Commission on Radiological Protection (ICRP) soon followed with a limit of 0.2 roentgen per day in 1934. In 1950, the ICRP reduced their recommended limit to 0.3 roentgen per week for whole-body exposure.

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?

Conversion Equivalence

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.
