Review I Constants I Periodic Table
The unit rem (roentgen equivalent for man) is the
product of the radiation dose in rads and the
relative biological effectiveness (RBE) of radiation.
The Sl unit for effective dosage is the sievert (Sv)
and 1 Sv 100 rem,
The intensity of radiation increases as you move closer to the radiation source according to the equation
dz?
