Table 2.
Summary of parameter values used in the Trinity assessment for estimation of activity concentrations on vegetation due to dry deposition of particles < 50 μm (from Bouville et al. 2020).
| Maximum interception | Foliar interception constant | Standing plant biomass | Interception fractiona | |
|---|---|---|---|---|
| Vegetation type | M (unitless) | α (m2 kg−1dry weight) | Ydry (kgdry weight m−2) | fdry (unitless) |
| Vegetables grown in gardens for local consumption | 0.85 | 2.8 | 0.3 | 0.48 |
| Fruit, berries, etc., directly exposed to fallout | 1 | 2.8 | 1 | 0.94 |
| Pasture grasses and vegetation grazed by livestock | 1 | 2.8 | 0.3 | 0.57 |
aCalculated from the information in the preceding columns, using eqn (3). The foliar interception constant α and standing plant biomass Ydry used by Bouville et al. (2020) are the same as the absorption coefficient μ and the standing plant biomass B, respectively, in eqn (3).
