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

Provides functions for radiation safety, also known as
"radiation protection" and "radiological control". The science of
radiation protection is called "health physics" and its engineering
functions are called "radiological engineering". Functions in this
package cover many of the computations needed by radiation safety
professionals. Examples include: obtaining updated calibration and
source check values for radiation monitors to account for radioactive
decay in a reference source, simulating instrument readings to better
understand measurement uncertainty, correcting instrument readings
for geometry and ambient atmospheric conditions. Many of these
functions are described in Johnson and Kirby (2011, ISBN-13:
978-1609134198). Utilities are also included for developing inputs
and processing outputs with radiation transport codes, such as MCNP,
a general-purpose Monte Carlo N-Particle code that can be used for
neutron, photon, electron, or coupled neutron/photon/electron transport
(Werner et. al. (2018) <doi:10.2172/1419730>).
