“REM” in italiano

An area in which radiation levels could result in an individual receiving a dose equivalent in excess of 0.1 rem per hour.

The rem takes account of a ‘quality factor’, which for the more dangerous alpha particles is 10.

According to Badhwar, the total increase in cosmonaut exposure was about 6 or 7 rem , a dose equivalent to 100 to 150 days of additional radiation exposure.

The modern international system of units includes the Gray, the Sievert, and the Becquerel (Bq); these replace the rad, rem , and Curie, respectively.
