What type of dosimeter is the DT-60?

The DT-60 is categorized as a non-self reading high range casualty dosimeter, which is specifically designed to measure higher doses of radiation. This type of dosimeter does not provide a direct reading of the radiation exposure on-site. Instead, it is a passive device that requires processing to determine the amount of radiation exposure it has recorded.

The non-self reading aspect means that users cannot immediately see how much radiation they have been exposed to without additional equipment or procedures, which is critical in high-dose situations where monitoring and health risk assessments are crucial after potential significant radiation exposure.

In contrast, other types of dosimeters listed in the options either measure lower ranges of radiation or provide immediate readings, which differs fundamentally from the function of the DT-60. The characteristics of the DT-60 make it particularly suitable for applications related to casualty monitoring in environments where high radiation exposure is expected, thereby reinforcing the importance of accurate dosimetry in health and safety protocols.
