Thermoluminescence in LiF induced by monoenergetic, parallel beam, 13.8- and 81.0-meV diffracted neutrons. The intrinsic TL response per absorbed neutron.

摘要: The thermoluminescent response of TLD-600 and TLD-700 to thermal neutrons has been measured by exposure a monoenergetic, parallel beam, 13.8- 81.0-MeV from Kandi-II diffractometer. integral TL in for neutron fluence 10/sup 10/ neutrons/cm/sup 2/ was, after correction self-shielding, equivalent the 1470 +- 90 4020 480 R (/sup 60/Co) at E/sub n/ = 81.0 13.8 MeV, respectively. From these results one calculates that n/cm/sup Maxwellian energy distribution T 293.6/sup 0/K would give an equal 2330 145 2630 315 60/Co). responds with 0.12 0.007 60/Co), which similarly implies signal 0.19 0.011 experimental are essentially free flux depression effects due backscattering. Monte Carlo calculations were carried out attempt correct previously published self-shielding. neutron-induced KERMA ismore » 0.135 0.01 times as effective /sup 60/Co-induced producing TLD-600.
