According to the death statistics in townships during 2014 to 2018 from the website on Ministry of Health and Welfare, the standardized cancer mortality rate (the number of deaths per 100,000 people) of Lanyu residents is similar to that of neighboring townships (Green Island, Taitung County’s Daren Township, Taitung City, Pingtung County’s Mudan Township, and Pingtung County’s Manchu Township). No abnormalities have occurred. Although there is no obvious reason to prove that (Lanyu) Low-Level Radioactive Waste Storage Site is related to the health status of nearby residents, in order to avoid unnecessary suspicion and eliminate doubts of villagers, Taiwan Power Company has adopted the most direct and practical method. Since 1999, the villagers were invited to the Radiation Laboratory of Taiwan Power Company’s No. 3 Nuclear Power Plant to measure the presence of artificial radioactive substances in the body. 4,423 people have accepted the test by the end of September 2017. The results show that no villagers were invaded by artificial radioactive nuclides. And the results have been sent to participants. Currently, the whole body measurement activity of the residents is changed to the annual Lanyu Township Youth Basketball Tournament in conjunction with Lanyu people's quick screening for radiation pollution.
In order to further reassure the residents of Lanyu, clarify the impact of (Lanyu) Low-Level Radioactive Waste Storage Site on the health of people, and promote the effectiveness of communication, the Ministry of Economic Affairs has entrusted the Ministry of Health and Welfare to handle the "Pioneer Research Project of Long-term Health and Safety Assessment of Low-Level Nuclear Waste on Lanyu Residents and Epidemiology". The project has been approved by the Executive Yuan and funded by the Ministry of Economic Affairs' Nuclear Backend Fund. The Ministry of Health and Welfare handles the health inspection of Lanyu residents. The period of the health checkups was from November 2018 to the end of August 2019. The total number of Lanyu residents that received health checkups is 2,500.
