| Abstract:: |
| Objective To estimate the annual tritium intake and the tritium committed effective dose to the public in the early 1990s. Methods The calculation was based on the tritium data obtained through a nation-wide investigation program on tritium concentration in Chinese foodstuffs,air and water.Dose coefficients given in ICRP 72 Publication and proper data on annual intakes of air,water and foodstuffs of the Chinese people were used for the estimation. Results The annual tritium intake through air,water and food pathways and the committed effective dose for Chinese adults,juveniles and infants are as follows,respectively: 16200, 11600 and 8040 Bq/a for the intake,and 0.53,0.52 and 0.75 μSv/a for the committed effective dose. Conclusion The annual committed effective dose to the Chinese adults,juveniles and infants mainly comes from food tritium,constituting about 87% of the total,paricularly from organically bound tritium. |
