3. Effect of Neutron Irradiation on Dosimetric Properties of the TLD-600H (Lif6:Mg,Cu,P)
Published: 11/1/2011
Authors: A A Romanyukha, Ronaldo Minniti, M. Moscovitch, Alan K Thompson, F. Trompier, Ronald Colle, A Sucheta, S. P. Voss, L. A. Benevides
Abstract: Ideally, dosimeters should measure the dose without their dosimetric properties being affected by the radiation type being measured. Industry-wide occupational radiation workers that can be potentially exposed to neutron radiation fields are routine ...
