Fraction of unfissioned plutonium deposited vs. distance

a. Using soil data supplemented by model estimates of deposition density.
Distance (km)	Unfissioned 239Pu deposited (%)	Cumulative (%)
0–10	5.0	5.0
10–30	3.9	8.9
30–100	53	62
100–200	19	81
200–300	1.4	82
300–500	0.4	83
>500	17	100
b. Using model estimates of plutonium deposition density only.
Distance (km)	Unfissioned 239Pu deposited (%)	Cumulative (%)
0–10	5	5.0
10–30	3.6	8.6
30–100	52	61
100–200	17	78
200–300	1.2	80
300–500	0.4	80
>500	20	100
