Abstract
In this work, one type of thermoluminescence dosimeter low density polyethylene grafted by acrylic acid acrylamide, acrylic acid actinamide polymer film (LDPE-g-p (AAm/AAc)) was irradiated by 60Co therapeutic gamma ray dose. This work deals with the case of sulfonated grafted film which has good properties such as thermal stability, and good dosimetric properties. The various sources of uncertainty for this type of thermoluminescence dosimeter under study were analyzed. The uncertainty budget tables for radiation measurements were declared. For the used procedure, these uncertainties multiply the coverage factor equal 2 to obtain the expanded uncertainty at 95% confidence level. The combined uncertainty does not exceed 6.3%. The results suggested that, the expanded uncertainty at 95% confidence level should be added to the value of measurements to obtain the accurate dose.
