Area Monitoring

Question 1

Area Monitoring Purpose

Answer 1

Record accessible areas to ensure that non-radiation workers do not exceed 500mrem per year and members of public are not exposed in excess of limits.

Duration of issue and collection coincides with issue period of DT-702/PD

Question 2

Environmental Monitoring Purpose

Answer 2

Areas accessible to the general public to verify members of the (GP) are not likely to exceed a TEDE of 100 mrem per year and external sources do not exceed 2 mrem in any given hour.

Question 3

Posting Dosimeter devices in nuclear propulsion areas

Answer 3

Personnel could receive high radiation exposure in the event of a nuclear critical accident include secondary shield of an operating reactor plant and where operations are performed that change reactivity

In spaces that are posted with TLD’s. DT-518/PD

Question 4

Monitoring Ambient photon/beta radiation is measured

Answer 4

DT-702/PD cards are placed in black holder in accessible areas immediately adjacent to restricted areas

Question 5

Monitoring ambient neutron is measured

Answer 5

DT-702/PD is placed in polyethylene cylinder that is essentially same size and design as AN/PDR-70 and mounted adjacent to restricted areas.

Designated Neutron Area Monitor, Two forms NAM-1 and 5 drawer NAM-5

NAM or BUMED area Monitor:

Monitor gamma and neutron levels in berthings outside nuclear WPN’s stowage

Question 6

Requirements for monitoring dental facility

Answer 6

Dental spaces are not required to issue personal dosimeter or conduct area monitoring

Dental repair technicians who service radiological equipment shall wear dosimeter

Personnel who operate cone-beam dental (CT) should receive radiation physicals and spaces monitored as appropriate.
