A4-4-4 Effective committed doses

The cloud resulting from the release can be considered dispersed by diffusion and deposition (Pasquill model). If a stability condition, F, is assumed with a 2 m s wind velocity and a deposition velocity of 0.01 m s the ground concentrations shown in Table A4-5 (roughly) result. [Pg.320]

The levels of ground contamination calculated above, can be compared with the contamination levels in a generic European country after Chernobyl, on the average equal to 10-20 kBq with peaks of 100-200 kBq (Vargo, 2000). [Pg.321]

On the assumption that the food chain is controlled after the accident and so the caesium intake is zero, the doses to the population can be due only to ground shine (if the population has not been evacuated). The doses at one year and at 50 years can be calculated on the basis of the factors shown in Table A4-6 corresponding to a contamination of 1 kBq (Vargo, 2000). [Pg.321]

Therefore, within a radius of 1 km from the site, multiplying the figures of the preceding table by 200, the results shown in Table A4-7 are obtained. [Pg.321]

At 10 km, the doses are given in Table A4-9. Krypton-85 effective doses [Pg.321]
