- The SI unit for radioactivity is the Becquerel (Bq)
- 1 Bq = 1 atomic disintegration per second (dps)
- 1 Bq = 2.7 x 10 -11 curie (Ci)
- 1 Ci = 3.7 x 1010 Bq
- 1 pCi/L = 1 x 10-9 m Ci/ml
- The SI unit for radiation is the sievert (Sv)
- 1 Sv = 100 rem
- Common Prefixes for units
- 10-3 = milli m
- 10-6 = micro m
- 10-9 = nano n
- 10-12 = pico p
- E.g., 1 picocurie (1 pCi) = 1 x 10-12 Ci
