... For example, not all the original developed films from film badges are available, particularly for some of the earliest test series. Incomplete records and poor penmanship in some original film badge records in archives have left ambiguities in assignment of some badge readings to particular individuals.

... It enabled the Committee to develop a relatively simple means for expressing the most probable radiation exposure received by a single film badge and the limits within which the exposure can be determined with 95% confidence. Applying methodology recently developed by the International Commission on Radiation Units and Measurements (ICRU 1985)

... Metallic filters used over film packets to establish more uniform film response varied during early test operations and generally were standardized in 1953 to have a 0.028-inch-thick lead filter. This filter was adequate for monitoring fission and activation-product photons over a wide range of energies (Section 4.A)

... , the approach developed is a reasonable method for combining biases and uncertainties from several different sources and for estimating the deep-dose equivalent from film badge readings. Although the specific values for bias and uncertainty given in this report are strictly applicable only to atmospheric test series participants, the methods used to obtain these values could be applied to other personnel monitoring situations such as underground testing at NTS after 1962 and similar monitoring under field conditions, or with revised uncertainties, to monitoring for reactor and hospital radiation workers.

... Deepdose equivalent is the quantity of interest in evaluating the potential for biological effects in an individual involved in the weapons test genes. Therefore, each of the individual series evaluations in Chapter 6 include an overall bias and uncertainty that will effectively provide a mechanism for conversion from exposure, as reported on the film badges, to deep-dose equivalent.
