Description
Technical Field
The invention belongs to the field of X-ray and gamma-ray radiation field measurement, and particularly relates to a combined type adjustable charged particle balance body of a pyroelectric dosimeter and an installation method thereof.
Background
The thermoluminescent dosimeter has the advantages of wide measuring range, small volume, low price, easy operation and the like, and is one of the most commonly used detectors for measuring the absorption dose of X-ray and gamma-ray radiation fields at present. Commercial thermoluminescent dosimeters mainly comprise two types, namely a lithium fluoride type and a calcium fluoride type. Charged particle balance is an important concept in radiation dosimetry, and only under charged particle balance conditions does the energy transferred to a mass of material during the interaction of uncharged ionized particles with the material be approximately equal to the energy actually absorbed in the mass of material. Therefore, for the measurement and calibration of the absorbed dose of the X-ray and gamma-ray radiation fields, the detector is encapsulated in a suitable charged particle balance, no matter what kind of detector is chosen.
Literature reports on charged particle balances of thermoluminescent dosimeters, which can be referred to as "linear upper limit and repeatability study of gamma-ray response of domestic LiF (Mg, ti) -M dose sheet" by Bai Xiaoyan et al, absorption dose measurement was performed in 60 Co irradiation experiments using an aluminum-box-packaged thermoluminescent dosimeter, a 2mm thick front panel provided charged particle balance conditions for the thermoluminescent dosimeter, and a 4mm thick rear panel to reduce back scattering. In another example, in GJB2165-94, a method for determining absorbed dose of an electronic device by using a thermoluminescent dose measuring system, caF 2:Mn is packaged as follows: when the scale irradiation source is 60 Co, the wall material can be aluminum with the thickness of 2.2 mm; in gamma ray and X ray irradiation tests, when the test source is 60 Co, if the low-energy scattered photon component in the radiation field is negligible, the wall material can be aluminum with the thickness of 2.2 mm; if the low-energy scattered photon component is larger, the wall material is a lead structure with 0.7-1mm of inner wall and 1.5mm of outer wall. The charged particle balance body in the existing literature is mainly used for 60Co calibration and irradiation experiments. Therefore, the existing method has defects in the aspects of universality and expansibility, and cannot meet the charged particle balance requirements in the measurement of absorption doses of radiation sources with different energy sections and broad spectrum radiation sources.
