[ RadSafe ] Collective Dose

[William Lipton]

Tracking collective dose, is very important in ensuring good radiological
work practices.  Without this, management would consider whether it's
cheaper to hire more workers instead of spending the money required for
engineering controls.  This is especially true for jobs which can be
performed by unskilled labor.  I've heard of situations where management
hired workers, burned them out quickly, and then replaced them.  These
workers were then unemployable as radiation workers for the rest of the
quarter.  This is NOT good health physics.

Collective dose is an important parameter for evaluating an ALARA program.
