\title{Calculate dose rate of slices in a spherical cobble}
\usage{
calc_CobbleDoseRate(input, conversion = "Guerinetal2011")
}
\arguments{
\item{input}{\link{data.frame} (\strong{required}): A table containing all relevant information
for each individual layer. For the table layout see details.}

\item{conversion}{\link{character} (\emph{with default}): dose rate conversion factors
to use, see \link{BaseDataSet.ConversionFactors} for the accepted values.}
}
\value{
The function returns an \linkS4class{RLum.Results} object for which the first element
is a \link{matrix} (\code{DataIndividual}) that gives the dose rate results for each slice
for each decay chain individually, for both, the cobble dose rate and the sediment
dose rate. The second element is also a \link{matrix} (\code{DataComponent}) that gives
the total beta and gamma-dose rates for the cobble and the adjacent sediment
for each slice of the cobble.
}
\description{
Calculates the dose rate profile through the cobble based on Riedesel and Autzen (2020).

Corrects the beta dose rate in the cobble for the grain size following results
of Guérin et al. (2012). Sediment beta and gamma dose rates are corrected
for the water content of the sediment using the correction factors of Aitken (1985).
Water content in the cobble is assumed to be 0.
