Current problems and expected improvements in personal neutron dosimetry.
Many technological activities involve the potential for worker exposure to neutrons. The determination of neutron personal dose equivalent is difficult due to a number of factors including the materials and methods used to evaluate the response of personal dosemeters and the quantities for expressing dose equivalent. Nevertheless, recent progress has been made in the development of devices and techniques for the measurement and calibration of neutron personal dosemeters. The quantities and units used to express neutron dose equivalent are being improved and clarified. Therefore, it is expected that a number of remaining difficulties with neutron dosimetry will be mitigated.
