    Abstract

    Since 1988, the International Agency for Research on Cancer (IARC) has classified radon among the compounds for which there is scientific evidence of carcinogenicity for humans (group 1). The World Health Organization (WHO) recommends a reference radon level between 100 and 300 Bq/m³ for homes. The objective of this study is to measure the radon concentrations in 401 workplaces, different from the patient rooms, in 28 different buildings of the university hospital in Bari (Apulia region, Southern Italy) to evaluate the exposure of health care workers. Radon environmental sampling is performed over two consecutive six-month periods via the use of passive dosimeters of the CR-39 type. We find an average annual radon concentration expressed as median value of 48.0 Bq/m³ (range 6.5-388.0 Bq/m³) with a significant difference between the two six-month periods (median value: February/July 41.0 Bq/m³ vs. August/January 55.0 Bq/m³). An average concentration of radon lower than the WHO reference level (100 Bq/m³) is detected in 76.1% of monitored environments, while higher than 300 Bq/m³ only in the 0.9%. Most workplaces report radon concentrations within the WHO reference level, therefore, the risk to workers' health deriving from occupational exposure to radon can be considered to be low. Nevertheless, the goal is to achieve near-zero exposures to protect workers' health.

    본 논문은 이탈리아 Bari 대학병원 내부 다양한 공간에서의 라돈양을 측정하고 여러 규제치(WHO, EPA 및 이탈리아 정부 규제치)와 비교평가 함으로서 병원 내부 종사자들의 연간 라돈 흡입량을 분석한 논문임.
    본 논문에서는 병원 내부 401개의 공간에서 분기별 라돈의 양을 측정하였으며, 굴뚝 효과를 고려하여 병원 건물 층수에 따른 라돈양의 변화를 추가로 측정하였음.
    측정 결과 평균적으로 연간 48.0 Bq/m3의 라돈이 측정되었음 (최소 6.5 Bq/m3, 최대 388 Bq/m3). 분기별 측정 결과에서는 1분기에서 가장 높은 라돈의 양이 측정되었고, 굴뚝 효과를 고려한 층별 결과에서는 지하에서의 라돈양이 가장 높게 측정되었음.
    401개 공간에서 측정된 라돈의 양은 이탈리아에서 규제하는 500 Bq/m3 보다 낮았고, 3개의 공간에서만 Bari 대학병원 지역규제치인 300 Bq/m3 보다 높게 측정되었음. 최종적으로 WHO에서 제공한 규제치를 고려할 때 76.1%의 공간에서 WHO 제한치보다 낮은 라돈양이 측정되었음.
