Application of prototype radiation portal monitor 15 based on IEC 62244:2019 with technology audit supporting detection of radioactive sources: A review

Radioactive materials that pollute the environment can interfere with the safety and security of a country. Detection of radioactive sources is needed to detect radioactive material contamination early. The National Nuclear Energy Agency (BATAN) has developed a prototype technology system that can monitor the presence of radioactive materials that interfere with safety, namely the Radiation Monitoring Portal (RPM). The RPM is fixed to screening or inspection of sources of gamma radiation and or neutrons automatically on goods, people, or vehicles that pass through the detection area, including RPM15, installed on the Main Gate Security (MGS) for the Pasar Jum’at Nuclear Area. Therefore, to ensure that the clearance function of nuclear technology is feasible or not to be used widely and commercially valid, a clearance mechanism through an RPM technology audit using the IEC 62244:2019 standardization. The research method used is a qualitative method from the technology audit literature study and conformity audit. The results show that the conformity audit of the radiation portal monitor 15 based on IEC 62244:2019 which fulfill the following requirements: a) radiation detection requirements include false alarms (clause 6.1), background effects (clause 6.2), gamma radiation detection (clause 6.3), Over-range indication (clause 6.6); b) climatic requirements include ambient temperature (clause 7.2), relative humidity (clause 7.3), Climatic exposure type test (clause 7.5); c) mechanical requirements include vibration (clause 8.1), Impact (microphonic) (clause 8.2); d) Electric and electromagnetic requirements include Electrostatic Discharge (ESD) (clause 9.1), Conducted disturbances (clause 9.4), Surge and oscillatory waves (clause 9.5), Line voltage and frequency fluctuations (clause 9.6). The non-conformity of the radiation portal monitor 15 based on IEC 62244:2019 requirements are neutron radiation detection (clause 6.4), Detection of neutron radiation in a high gamma field (clause 6.5), Dust and moisture protection (clause 7.4), Radiofrequency (RF) (clause 9.2), Radiated emission (clause 9.3) and documentation (clause 10) for Operation and maintenance manual (clause 10.1), Test certificate (clause 10.2), Declaration of conformity (clause 10.3) to meet the requirements of technology audit objectives including improvement, compliance, prevention, positioning, planning, and technological investigations to protect the public and the environment from exposure to inappropriate use of radioactive materials
