| Abstract | ||||
| Measuring radiation dose in a mixed radiation field cannot be performed by using only one dosimeter, but a pair of dosimeters TLD600 and TLD700 can be successfully used to estimate that radiation dose. Therefore, in the present study, the response of TLD600 and TLD700 to neutron/gamma mixed radiation field was deeply discussed. Moreover, the sensitivity and stability of TLD600 and TLD700 were studied. A strong correlation between TL output signal intensity of TLD700 to gamma dose was appeared, with a linear coefficient of R2 = 0.99. Likewise, a strong correlation between TL output signal intensity of TLD600 to gamma dose and neutron irradiation was also appeared, with a linear coefficient of R2 = 0.99. Thus, TLD700 can be applied to measure gamma dose with good sensitivity, while TLD600 can be applied to measure both gamma and neutron dose. Hence, a combination of TLD700 and TLD600 can be successfully employed to assess the radiation doses characterizing a mixed radiation field of neutron and gamma rays. | ||||
