dc.description.abstract | In the CBRN (chemical, biological, radiological and nuclear) environment, the response measures early warning, protection, reconnaissance, decontamination, and first aid. Among all the measures, early warning is the most important of all. While facing the so-called poor man’s atomic bomb-chemical warfare agents, troops in the front line rely heavily on alarming equipment as their early warning measures. However, both M8A1 and GID-3 alarming equipment, currently serve in ROC armed forces, are using radioactive materials to ionize incoming gas to detect chemical warfare agents and chemical substances. The ionizing radiation generated by the radioactive materials can be a potential harm for the alarming equipment operators. Thus, we must measure and assess their radiation doses to ensure operators’ safety. This study uses optically stimulated luminescence dosimeters (OSLDs) which are placed on the surface of equipment and in the storage unit to measure the cumulative dose over 2000 hours, which is the annual legal working hours in Taiwan. Also, all the annual military routine activities that require alarm equipment to be operated for long hours such as unit trainings, professional expertise trainings, evaluations, military exercise, and equipment maintenance are considered and the total operation hours to make sure that operators are in the safe environment. After continuously monitoring M8A1 and GID-3 for 2000 hours, the average dose rates of two equipments are 0.59 μSv/h and 0.12 μSv/h respectively. Since the total operation time of the annual military routine activities is 1376.5 hours, annual cumulative doses for the operators are 905.3 μSv and 184.1 μSv, which are lower than the legal annual dose limit (1000 μSv). Hence, there is no need to implement special medical examinations or individual radiation dose monitoring. In conclusion, both M8A1 and GID-3 alarming equipment are safe enough for operators to implement in various annual military routine trainings. | en_US |
