Unlike film badges, pocket dosimeters provide no permanent, legal record of exposure.
It also must be understood that the common film badge is nothing more than a piece of dosimetry film between two small metal filters surrounded by a plastic holder.[1] Although this device is sensitive to the effects of ionizing radiation, it is equally sensitive to various other influences.
Improper storage of the film badge also can create exposure readings that are inaccurately elevated.
When the soldiers' film badges recorded unsafe levels of radioactivity, the men were told to take multiple showers and change their clothes.
A mid-1950s National Bureau of Standards test found that several laboratories erred by plus-or-minus-100 percent in their reading of film badges similar to those used at Crossoards.
