Sievert – UPSC Prelims

Sievert (Sv):
  • Sievert is the unit of radiation absorption in the International System of Units (SI).
  • The sievert takes into account the relative biological effectiveness of ionizing radiation.
  • When the physical energy absorbed by tissues from x-rays, gamma rays or electrons is one Joule/kg, the biologically effective dose is considered to be one Sv.
  • Since Sv is a huge unit, specialists use milliSv or “mSv”(one-thousandth of an Sv) as a unit.
  • Skin dose in a chest x-ray exam is about 1 mSv.
