Which two dosimeters are specified for use in the described policy?

• A. TLD And EPD
• B. TLD And OSL
• C. OSL And Film Badge
• D. Ring Badge And TLD

Answer: (A)

The main idea is that the policy requires two dosimeter types to cover both cumulative dose tracking and real-time exposure awareness. The two specified are thermoluminescent dosimeters (TLD) and electronic personal dosimeters (EPD).

TLDs measure the total radiation dose over a monitoring period and store energy in a crystal, which is read after the period to give an accurate, archival record of occupational exposure. They’re reliable for documenting the dose an individual has received over time and are useful for regulatory compliance and dose history.

EPDs provide immediate dose readings and can alert you with alarms when exposure levels are rising, enabling real-time decision-making to reduce exposure during tasks.

Using both together ensures you have a precise record of accumulated dose (from the TLD) while also having live feedback to manage current exposure (from the EPD). The other options don’t align with this policy because they pair dosimeters that aren’t specified together for this purpose.
