With the aim of improving the monitoring of workers potentially exposed to neutron radiation in Brazil, the IPEN/CNEN-SP in association with PRO-RAD designed and developed a passive individual gamma-neutron mixed-field dosemeter calibrated to be used to (241)AmBe sources. To verify the dosimetry system response to different neutron spectra, prototypes were irradiated with a (252)Cf source and evaluated using the dose-calculation algorithm developed for (241)AmBe sources.
为了改进对巴西可能接触中子辐射的工人的监测，巴西核能与能源研究中心/巴西国家核能委员会圣保罗分中心（IPEN/CNEN-SP）与辐射防护协会（PRO-RAD）联合设计并开发了一种被动式个人伽马-中子混合场剂量计，该剂量计经过校准，可用于（241）镅铍源。为了验证剂量测定系统对不同中子能谱的响应，使用（252）锎源对原型进行了辐照，并使用为（241）镅铍源开发的剂量计算算法进行了评估。
