Radiation: Units of Measure

Two Sets of Units Used for Measuring Radiation

What Is Measured	Conventional Unit Used in the U.S.	International System of Units (SI) Used in Japan	Example
Radioactivity	Curie (Ci)	Becquerel (Bq)	320 Bq/kg
Exposure	Roentgen (R)	Coulomb/kilogram (C/kg)	Example
Absorbed Dose	Radiation Absorbed Dose (rad)	Gray (Gy)	Example
Dose Equivalent	Roentgen Equivalent Man (rem)	Sievert (Sv)	5 Sv

Prefix	Equal to	?	Abbreviation	Example
micro-	1 X 10^-6	.000001	μ	6,000,000 μSv
milli-	1 X 10^-3	.001	m	= 6,000 mSv
centi-	1 x 10^-2	.01	c	= 600 cSv
				= 6 Sv
