Response of⁶LiF:Mg,Cu,Si and⁷LiF:Mg,Cu,Si TLD Pairs to the Neutrons and Photon Mixtures

Abstract

LiF:Mg,Cu,Si held in Harshaw neutron TLD badge holders for the dosimetry in the mixed field of neutron and gamma rays was found to be less than 0.1 as against the maximum permitted value of 0.4.

Characterization of the Secondary Neutron Field Produced in a Thick Aluminum Shield by 1 GeV/u 56Fe Ions Using TLD-Based Ambient Dosimeters

“…The two TLD600 chips, enriched in 6 Li, can detect photons, charged particles and thermal neutrons (through the 6 Li(n, α) 3 H reaction), while the two TLD700 chips, where the 6 Li fraction has been depleted, respond identically to the TLD600 to gamma radiation and charged particles but are not as sensitive to thermal neutrons. This allows a separation of the neutron TL signal in a mixed radiation field by subtraction of the TLD700 signal from the one measured by the TLD600 [26][27][28]. The readout procedure of the TLD600H/700H crystals is described in the Supplementary Material.…”
