hvl {radsafer}

half-value layer and tenth-value layer computations

Description

Derive hvl and tvl from radiation values through a material thickness.

Usage

hvl(x, y)

Arguments

x

material thickness

y

radiation measure through the material

Value

a data frame with the inputs, followed by the computed values for attenuation coefficient (listed as "mu"), half-value layer (hvl), tenth-value layer (tvl), and the homogeneity coefficient (hc) which is the ratio of a half-value layer to the following half-value layer.

Examples

H50_ex <- data.frame("mm_Al" = 0:5, "mR_h" = c(7.428, 6.272, 5.325,4.535, 3.878, 3.317))
hvl(x = H50_ex$mm_Al, y = H50_ex$mR_h)
