A New Approach to Low-Level Monitoring in Mixed Radiation Fields

The new method for measuring ambient dose equivalent in mixed neutron-gamma fields has been proposed. It has been shown that the moderator technique, up to now used for neutron monitoring only, can be adjusted for monitoring both gamma and neutron radiation. The fluence response of a device consisti...

Description
Summary:The new method for measuring ambient dose equivalent in mixed neutron-gamma fields has been proposed. It has been shown that the moderator technique, up to now used for neutron monitoring only, can be adjusted for monitoring both gamma and neutron radiation. The fluence response of a device consisting of a 3He proportional counter and 203 mm diameter polythene sphere has been evaluated and compared with the ambient dose equivalent conversion factors for photons.
