Standard Practice for Use of a Thermoluminescence-Dosimetry System (TLD System) for Radiation Processing

Importancia y uso:

4.1 In radiation processing, TLDs are mainly used in the irradiation of blood products (see ASTM Practice 51939) and insects for sterile insect release programs (see ASTM Guide 51940). TLDs may also be used in other radiation processing applications such as the sterilization of medical products, food irradiation, modification of polymers, irradiation of electronic devices, and curing of inks, coatings and adhesives. (See ASTM Practices 51608, 51649, and 51702.)

4.2 For radiation processing, the absorbed-dose range of interest is from 1 Gy to 100 kGy. Some TLDs can be used in applications requiring much lower absorbed doses (for example, for personnel dosimetry), but such applications are outside the scope of this practice. Examples of TLDs and applicable dose ranges are given in Table 1. Information on various types of TLDs and their applications can be found in Refs (1-10).7

(A) This table is taken from Ref (6). Ranges are approximate, and may vary with batch. Supralinearity refers to a region where the slope of the response versus dose curve is greater than that for the linear region.

4.3 Information on other dosimetry systems used for radiation processing can be found in ICRU Report 80.
