Beta reduction factors for protective clothing at the Oak Ridge National Laboratory
Beta reduction factors (f{sub {beta}}) for protective clothing (PC) at the Oak Ridge National Laboratory (ORNL) have been determined for a variety of protective clothing combinations. Data was collected to determine the experimental f{sub {beta}} for several combinations of PCs under laboratory conditions. Radiation dose rates were measured with an open window Bicron{reg_sign} RSO-5 ion chamber for two distinct beta energy groups (E{sub max} = 1.218 {times} 10{sup {minus}13} J(0.860 MeV) and 3.653 {times} 10{sup {minus}13} J (2.280 MeV)). Data points determined, as the ratio of unattenuated (no PCs) to attenuated (PCs), were used to derive a set of equations using the Microsoft{reg_sign} Excel Linet function. Field comparison tests were then conducted to determine the validity of these beta reduction factors. The f{sub {beta}} from the field tests were significantly less than the experimental f{sub {beta}}, indicating that these factors will yield conservative results.
