주택 라돈 저감의 건강 효과와 사회적 편익 = Health Effects and Social Benefit of Residential Radon Reduction

다국어 초록 (Multilingual Abstract)

Radon is a radioactive gas that causes lung cancer deaths. The contingent valuation method (CVM) is used to estimate the value of a statistical life(VSL) of 2.054 billion won for the death due to residential radon in Korea. Residential radon is assumed to have caused 2,330 deaths in 2020, of which the estimated social cost is 4.78 trillion won. When a national compulsory standard of 200Bq/m3 is set for residential radon concentration, the number of lives saved is estimated to be 691, leading to a social benefit of 1.42 billion won. This study reports the origin, characteristics and health risk of residential radon, and emphasizes the importance of a dramatic increase in the budget for residential radon reduction policies.

국문 초록 (Abstract)

라돈은 폐암사망 위험을 일으키는 방사성 가스이다. 본 논문은 조건부가치측정법(CVM)을 이용하여 우리나라 주택에서의 라돈 노출로 인한 사망자의 통계적 생명가치(VSL)를 20억 5,373만 원으로 추정하였다. 2020년의 경우, 주택 라돈으로 인한 사망자 수는 2,330명, 그 사회적 비용은 4조 7,836억 원으로 추정하였다. 주택에 대한 국가 라돈 농도 규제기준을 200Bq/m3로 설정하면 691명의 사망자 수가 감소하여 1조 4,191억 원의 사회적 편익이 발생하는 것으로 나타났다. 본 논문은 주택 라돈 노출의 원천과 특징 및 건강위해성(health risk)을 상세히 논하고 주택 라돈 저감을 위한 정책 예산의 획기적인 증액이 중요함을 강조하였다.
