"5.6 roentgens per second (R/s)The ionizing radiation levels in the worst-hit areas of the reactor building have been estimated to be 5.6 roentgens per second (R/s), equivalent to more than 20,000 roentgens per hour. " 20,000 roentgen = 200sv, fatal within ~1.42 seconds.
The roentgen equivalent man (rem) is a CGS unit of equivalent dose, effective dose, and committed dose, which are dose measures used to estimate potential health effects of low levels of ionizing radiation on the human body. Quantities measured in rem are designed to represent the stochastic biological risk of ionizing radiation, which is primarily radiation-induced cancer. These quantities are derived from absorbe… Web16 nov. 2024 · How many roentgens per hour are safe? A dose rate of 100 microR/hr (1 microGy/hr) is not dangerous. If this dose rate is accurate, living in it continuously (8760 hours per year) will give you a radiation dose of about 0.9 R/hr (9 mGy/yr). How much mSv is too much? Radiation exposure is commonly measured in millisieverts (mSv).
The roentgen has its roots in the Villard unit defined in 1908 by the American Roentgen Ray Society as "the quantity of radiation which liberates by ionisation one esu of electricity per cm of air under normal conditions of temperature and pressure." Using 1 esu ≈ 3.33564×10 C and the air density of ~1.293 kg/m at 0 °C and 101 kPa, this converts to 2.58 × 10 C/kg, which is the modern value given by NIST.
