The physical method was based on film badge
individual monitoring and irradiation of a simulator of a left hand containing thermoluminescent dosimeters.
The oldest and best-established personnel dosimeter is the film badge
; others include the optically stimulated luminescent (OSL) dosimeter, the pocket ionization chamber and the thermoluminescent dosimeter (TLD).
We have heard earlier, in the briefing film, that film badges
will be worn to determine the amount of individuals' radiation exposure, and "you'll be moved out in time to avoid sickness."
In addition to film badges
worn at the collar level, nuclear medicine technologists also wear ring badges to measure radiation dose received as a result of handling radioactive materials.

The film badge
cannot measure exposures less than 10 mR.
In diagnostic radiography, approximately 95% of the radiologic technologist's film badge
readings are directly related to radiation exposures received during image-intensified fluoroscopy and portable radiographic examinations. The average output intensity from an unshielded fluoroscopy unit is about 500 mR/hr at a distance of 1 foot from the radiation source. (The hour reflects only the actual accumulation of 60 minutes of radiation usage or the "fluoro-time.")
The document was an AWRE health physics paper looking at ways of testing the film badges
to be sure they were accurate.
