A fission chamber was used to measure 1451000100016 the neutron spectral fluences. 1451000100017 ANALYSIS Calculated gas-to-wall absorbed dose conversion 1451000100018 factors were used to deduce absorbed doses in the 1451000100019 walls, which are approximately equal to kerma. 1451000100020 ERR-ANALYS (ERR-T) Total uncertainty 1451000100021 (ERR-S,,2.)
