About These Units

Sievert (Sv)

The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.

Millirem (mrem)

A millirem (mrem) equals 0.001 rem or 10 μSv. US dosimetry standard: natural background 300-400 mrem/year, occupational limit 5,000 mrem/year, public limit 100 mrem/year above background. Chest X-ray: ~2 mrem.
