PERSONNEL RADIATION MONITORING

Radiation can bombard the body from sources outside the body and from sources within the body.

Various types of personnel radiation monitoring devices and programs are used to assess each individual's external and internal exposure to radiation.

The type of monitoring device or program used depends on the radiological hazards present.

These devises do not protect you from radiation but provide a means of determining how much radiation you have received.

Personnel Monitoring Devices

Common types of external dosimetry used to assess personnel doses from external sources of radiation:

Thermoluminescent dosimeter (TLD)

Pocket Ionization Chamber (PIC)

Electronic Dosimeter

Nuclear Accident Dosimeter

First responders involved in emergencies involving potential radiation exposure should be issued external dosimeters.

Correct Use of Dosimeters

Dosimeters are normally worn between the waist and the neck

Dosimeters should be kept uncovered by any material and not be opened

First responders should wear dosimeters inside their protective clothing, but outside their personal clothing

Some dosimeters (e.g., pocket ion chambers) are shock, temperature, and sunlight sensitive and should not be left in the car on the dashboard (66° C) or in direct sunlight for long periods.
