mcnp_sdef_erg_line: Produce MCNP source terms from ICRP 107 data

Description

Obtain emission data from the RadData package and write to a file for use with the radiation transport code, MCNP.

Usage

mcnp_sdef_erg_line(
  desired_RN,
  rad_type = NULL,
  photon = FALSE,
  cut = 0.001,
  erg.dist = 1,
  my_dir = NULL,
  write_permit = "n"
)

Value

a data frame can be saved to memory if desired (i.e. by my_file <- mcnp_sdef_erg_line(...)). For use with MCNP, a text file, 'si_sp.txt' is written to working directory. If file already exists, it is appended. The file contains all emission energies in the si 'card' and the Line indicator, L is included, e.g. si1 L 0.01 (showing a first energy of 0.01 MeV). This is followed by the emission probability of each si entry. An additional text entry is made summing up the probabilities.

Arguments

desired_RN

Radionuclide in form "Ba-137m"

rad_type

Radiation type, leave NULL if selecting photons or select from: 'X' for X-Ray 'G' for Gamma 'AE' for Auger Electron 'IE' for Internal Conversion Electron 'A' for Alpha 'AR' for Alpha Recoil 'B-' for Beta Negative 'AQ' for Annihilation Quanta 'B+' for Beta Positive 'PG' for Prompt Gamma 'DG' for Delayed Gamma 'DB' for Delayed Beta 'FF' for Fission Fragment 'N' for Neutron

photon

'Y' to select all rad_types that are photons

cut

minimum energy, defaults to 1e-3 MeV

erg.dist

energy distribution number for MCNP input

my_dir

Optional directory. The function will write an output text file, si_sp.txt to the working directory by default.

write_permit

Set this to 'y' to allow writing output to your directory.
