摘要

用Al2O3:C、LiF:Mg

Ti、LiF:Mg

P热释光剂量计（TLD）测量湛江市区本底辐射的热释光响应

以选取适合低辐射场辐射剂量测量的TLD。它们的最低响应剂量依次为Al2O3:C（1–2μGy）、LiF:Mg

P（约2μGy）和LiF:Mg

Ti（>10μGy）。Al2O3:C的热释光峰温较低

对较长时间段（>30 d）的累积剂量

存在较明显的热释光衰退

剂量响应曲线偏离线性;LiF:Mg

P和LiF:Mg

Ti的发光峰温较高

数年内都很稳定。综合考虑灵敏度和稳定性

LiF:Mg

P更宜于低辐射场的累积剂量测量。

Abstract

To select thermoluminescent dosimeters(TLDs) for low radiation research

thermoluminescence responses of Al2O3:C

LiF:Mg

Ti and LiF:Mg

P were measured under natural radiation background in Zhanjiang city

China.TL sensitivity of the three TLDs

in terms of the threshold dose

is sequenced as Al2O3:C(1~2 μGy)

LiF:Mg

P(about 2 μGy)

and LiF:Mg

Ti(>10 μGy).However

as the temperature of glow peak of Al2O3:C is not so high

its TL decays in a relatively long period

hence the non-linearity of the TL dose response curve of Al2O3:C

while temperatures of glow peaks of LiF:Mg

Ti and LiF:Mg

P are higher

hence their linear TL dose response.Therefore

LiF:Mg

P is the best TLD for low radiation cumulative dose detection.
