In 2001, the Radiation Protection Institute of ENEA promoted an Italian intercomparison exercise on internal dose assessment addressed to the qualified experts in radiation protection, following the coming into force in Italian law of the EURATOM 96/29 Directive. Five case studies of occupational exposure related to the Italian situation are used. The considered radioisotopes are: 60Co, 89Sr, 125I, 131I, and 222Rn + NORM (238U-235U-232Th). Data related to WBC, thyroid and urine excretion measurements, as well as radionuclide air concentration in the workplace, are provided to the participants. The results related to medical, industrial and Rn occupational exposure are well represented as means of log-normal distributions with values of the geometric standard deviation less than 2. A wider spread of results is present for the evaluation of occupational exposure to NORM.
2001年，在欧洲原子能共同体96/29号指令在意大利法律中生效后，意大利国家新技术、能源和可持续经济发展局辐射防护研究所针对辐射防护领域的合格专家开展了一次意大利内部剂量评估比对活动。使用了五个与意大利情况相关的职业照射案例研究。所考虑的放射性核素为：60Co、89Sr、125I、131I以及222Rn + 天然放射性物质（238U - 235U - 232Th）。向参与者提供了与白细胞、甲状腺和尿液排泄测量相关的数据，以及工作场所的放射性核素空气浓度数据。与医疗、工业和氡职业照射相关的结果很好地以对数正态分布的均值表示，几何标准差的值小于2。对于天然放射性物质职业照射的评估，结果分布范围更广。
