自1950年以来，在塞拉菲尔德工厂使用胶片徽章进行了外部辐射的个人监测，结果记录在约20，000名工人的外部剂量记录中。本文认为，可能的不确定性，在记录的光子剂量考虑到主要特点的类型的电影徽章上使用的网站和他们的表现在工作场所的辐射领域。总的来说，它的结论是，记录的累积年光子剂量应该是在一个因素的2的真实剂量相比，一个理想的剂量计的响应，而记录的年剂量更有可能是一个高估，而不是低估注意到可能的影响的徽章，存储剂量和输入的名义剂量的检测极限的记录。
Individual monitoring for external radiation has been carried out on the Sellafield Site using film badges since 1950 with the results recorded in external dose records for about 20,000 workers. This paper considers the likely uncertainties in the recorded photon doses taking into account the main characteristics of the types of film badge used on the site and their performance in the radiation fields found in the workplace. Overall, it is concluded that the recorded cumulative annual photon doses should be within a factor of 2 of the true dose in comparison to the response of an ideal dosemeter, while the recorded annual dose is more likely to be an overestimate rather than an underestimate noting the possible influences of limit of detection of the badge, storage dose and the entry of notional doses onto the record.
