Sieverts radiation dose

WebOne way to measure radiation is to measure the dose of radiation received, i.e. the effect it has on human tissue, which is measured in sieverts, abbreviated as Sv. As 1 sievert represents a very large dose the following smaller units are commonly used; Millisieverts, one thousandth of a sievert and abbreviated as mSv (1000mSv = 1Sv) Or WebFor example, citing a recently much reported example from Fukushima, converting an equivalent dose rate of 100 milliSieverts per hour to the Rem/hr domain, multiply 100 X 100 = 10,000, keep the milli prefix, and substitute rems for Sieverts. The result, of course, is 10,000 millirems per hour, or 10 rems/hr.
