Abstract
A radiation dosimeter includes a first radiation detector configured to operate in a counting mode, and a second radiation detector configured to operate in a current mode. A processor is configured to calculate a first detected dose of the first radiation detector, a second detected dose of the second radiation detector, and a total dose value using the first detected dose and the second detected dose. An alarm indicates when the total dose value is above a predetermined level.
