Which monitoring devices can radiographers use to record their monthly exposure to radiation?

The use of thermoluminescent dosimeters (TLDs) and optically stimulated luminescence (OSL) dosimeters is highly effective for recording monthly radiation exposure for radiographers. These devices effectively capture and store data on the amount of ionizing radiation received over a specific period.

TLDs work by absorbing radiation energy and then releasing that energy as light when heated. This light is measured to calculate the dose received. OSL dosimeters function similarly but use different materials that are optically stimulated to release the stored energy. Both types offer precise measurements and a longer lifespan compared to other monitoring options, making them ideal for routine monitoring of radiation exposure.

In contrast, options such as a Geiger-Muller counter and ionization chamber are primarily used for detecting and measuring radiation levels in real-time rather than for personal dose monitoring over months. While a film badge can provide dose information, it has limitations in sensitivity and stability compared to TLD and OSL technology, particularly over extended periods. Therefore, TLDs and OSL dosimeters are considered the best choices for accurate monthly exposure tracking in radiographers.
