Abstract:
A dosimeter includes a radiation detector and a display. The radiation detector outputs a signal indicative of an instantaneous radiation level. The dosimeter determines and displays a percent of limit (POL) value and/or a time to limit (TTL) value. The POL value indicates a ratio of an accumulated exposure to an exposure threshold. The TTL value indicates an amount of time estimated until the accumulated exposure exceeds the exposure threshold. The display may includes information indicative of both the POL parameter and the TTL parameter. The display may also display the instantaneous radiation level and/or a graphical representation of the instantaneous exposure level. The graphical representation might include a set of LED's arranged in a line wherein the number of activated LED's indicates the instantaneous exposure level. The display might also indicate a scale associated with the set of LED's. The dosimeter might include a switch to select one of multiple operational modes where the POL parameter and the TTL parameter are determined in part by the operational mode.
