Abstract
Radioactivity levels by the fission of radium series were different in regions and seasons. Accordingly, amounts of /sup 210/Po were different in these environments, and it transfered into tobacco leaves of raw material. Furthermore, the amount of /sup 210/Po in tobacco leaves was changed a little by manufacturing process of tobacco after the harvesting, and /sup 210/Po was concentrated in the manufactured goods. The /sup 210/Po in tobacco was absorbed into the human body by smoking, was transfered into the lung, and was accumulated. Accumulated /sup 210/Po releases alpha ray and becomes low accumulated dose. When this low accumulated dose distributes out of balance in the body, it becomes large exposure dose at some local sites, and makes a problem of carcinogenesis risk. The above-mentioned process was persued from the data of literature and was discussed.
