A dosimeter must measure a range between which values?

A dosimeter is a device used to measure exposure to ionizing radiation. The correct range of a dosimeter is determined by the application and the potential radiation levels the wearer may encounter.

The chosen answer indicates that the dosimeter must measure from 0 to 200 mR, which is equivalent to 0 to 2 mSv. This range is appropriate for environments where moderate radiation exposure might occur, providing sufficient sensitivity to detect doses that could be of concern while still maintaining a ceiling that protects users from being overwhelmed by excessively high readings.

This range is practical and useful in many occupational settings involving radiation, allowing individuals to monitor their exposure adequately without unnecessary complexity or concern about overexposure from readings that are too high or too low.

In contrast, the other options offer lower ranges that may not be adequate for detecting the levels of radiation typically encountered in various professional and medical situations. For instance, a maximum of 100 mR may be too limiting for certain work environments, while 50 mR could miss significant exposure.... Hence, the specified range of 0 to 200 mR effectively balances sensitivity and coverage for radiation safety monitoring.
