Abstract :
A personnel dosimetry system has been developed to satisfy the protection needs of nonregistered radiation workers in hospitals and nuclear installations. It consists of up to 200 special badges, each containing a charged electret film, and a microprocessor-controlled reader unit which calculates the cumulative radiation dose by measuring the surface potential of the electret noninvasively. A badge can read frequently without destroying the cumulative information on dose
