There is much less data, and much more controversy, regarding the possibility of cardiac and teratogenic effects, and the modelling of internal dose. [11] The ICRP recommends limiting artificial irradiation of the public to an average of 100 mrem (1 mSv) of effective dose per year, not including medical and occupational exposures. [3] The roentgen , abbreviated R, is the unit of radiation exposure. One roentgen corresponds to 2.58E-4 coulomb per kg of ions generated in air and an exposure of one coulomb per kilogram is equivalent to 3876 roentgens. Time: 15,000 Roentgens per hour won’t amount to much if you’re only exposed for a few seconds. For reference, a CT scan is about 300-400 Roentgens per hour, but you’re not going to sit in a running CT scanner for an hour. Shielding: the more mass you put in between you and the source, the less radiation will reach you.
Decades ago, this unit used to be one of the most popular ones, but recently, since the volumes of information Conversion of units between 1 Sievert (Si Unit) and Röntgen Equivalent Man (1 Sv and rem) is the conversion between different units of measurement, in this case it's 1 Sievert (Si Unit) and Röntgen Equivalent Man, for the same quantity, typically through multiplicative conversion factors (Sv and rem). Convert equivalent dose units. Easily convert millisievert to sievert, convert mSv to Sv . Many other converters available for free.

The body will heal and repair some of the damage if the exposure is received gradually, allowing larger total doses. Roentgen’s are another measure, 1 Roentgen (R) equals 0.877 rem or 0.00877 Sieverts. 150-200: Debris heap at the place of circulation pumps: 100:
roentgen (R) * SI Units: International System of Units Note: In the table above the common units and SI units in each row are not equivalent in value, i.e., 1 curie does not equal 1 becquerel, but they both measure the same parameter. roentgen/hour to sievert/second (R/h—Sv/s) measurement units conversion. Sources and Uses. Ionizing radiation can be present in the environment due to natural causes, or it could be artificially introduced into the environment by placing radioactive substances there.

For equivalent dose, the unit corresponding to rads is the rem (roentgen equivalent man). If the absorbed dose is in grays then the unit for dose equivalent is sievert (Sv). Thus, 1 Sv = 100 rem.
