People travelling by air will receive more exposure dose and by water will receive less one. According to statistic data from the Ministry of Communications in 1988, the turnover in that year was about 2x10¹⁰ man·km. The total number of fishermen for inshore fishing was nearly two million reported by Ministry of Agriculture, Animal Husbandry and Fishery. Based on measured data on 212 points in six typical shipping lines of inshore lines and inland rivers, and the total voyage is 5625 km, the average natural radiation dose rate received by travellers was calculated. From that assessment of collective effective dose for passengers by water and fishermen was derived. The value is 32.7 man·Sv for passengers and 265.3 man·Sv for fishermen.
