How do film badges compare to OSL and TLD badges in terms of sensitivity?

Film badges are known to have lower sensitivity compared to Optically Stimulated Luminescence (OSL) badges and Thermoluminescent Dosimeters (TLD). This is primarily due to the technology used in these detec

Film badges rely on photographic film to capture radiation exposure, which requires a significant amount of radiation to produce a measurable effect. As a result, they may not detect lower levels of radiation as effectively as OSL and TLD badges, which can measure smaller doses due to their advanced materials and mechanisms.

OSL badges utilize materials that luminesce when stimulated by light after being exposed to radiation, allowing for very precise measurements, even at low exposure levels. TLD badges work similarly but utilize materials that emit light when heated; they are also capable of measuring low doses of radiation accurately. Both OSL and TLD technologies provide a higher degree of sensitivity and allow for more accurate dose assessments across a wider range of radiation levels.

In summary, the comparison shows that film badges have a limited response to various levels of radiation and are less sensitive than OSL and TLD badges, making them less suitable for environments where precise radiation monitoring is crucial.
