Abstract
In a previous paper, we reported on the yearly trends during 1973-1983 in the occupational deaths in seven categories of industry in Japan (forestry, fisheries, mining, construction, manufacturing, transportation and communication, and electricity, gas, water, steam and hot water supply). The accidental average death rate in seven occupational industries was 141per million per year. In the present study, these data were extended to 1990. The accidental death rate of all seven industries showed a tendency of decrease year-by-year. However, the accidental death rate of mining was still high (821per million per year) and then has decreased in forestry, fisheries, construction, the most safety industry being electricity and others supply (19per million per year). The averaged accidental death rate of all seven industries during 1984-1990 was 85per million per year. Trends with time in fatal accident rate during 1973-1990 were calculated about 1.86per annual change in forestry and 4.87 in electricity and others supply, respectively. Compared with those figures in ICRP or other countries, the accidental death rates in industries in Japan were more rapidly decreased.
