The Center for Radiation Protection Knowledge provides downloadable models, data files, computer codes, and help files that provide ready access to data of interest in the radiation protection of workers and members of the public. This collection includes the models, elemental and radionuclide data, and supporting documentation necessary to describe the behavior of inhaled or ingested radionuclides.
Please refer any technical questions about the models, databases, or documentation to Dr. Keith Eckerman.
Rad Toolbox v. 3.0.0 (5/1/2014)
This toolbox provides ready access to data of interest in radiation protection of workers and members of the public. This package was developed for the U.S. Nuclear Regulatory Commission and is documented in ORNL/TM-2004/27. The software runs on a PC under Windows 98/NT/2000/XP to provide access to the data through a single GUI. The data include dose coefficients for intakes of radionuclides, exposure to radionuclides distributed in the environment, and for exposures to photon and neutron radiation fields. Other supportive data include interaction coefficients for alpha, electron, photon and neutron radiations, nuclear decay data, biological and physiological data, and supplemental information on various topics. The ORNL TM report is included in the download. During the installation elect to ignore any messages regarding file updates. The NRC Rad Toolbox Web page is located at: http://www.nrc.gov/about-nrc/regulatory/research/radiological-toolbox.html.

DCAL System v. 8.4 (11/1/2006)
DCAL is a comprehensive software system for the calculation of tissue dose and subsequent health risk from intakes of radionuclides or exposure to radionuclides present in environmental media. DCAL was developed for the U.S. Environmental Protection Agency and is documented in ORNL/TM-2001/190. The software runs on a PC under Windows 98/NT/2000/XP. The system includes extensive libraries of biokinetic and dosimetric data and models representing the current state of the art. DCAL maybe used either in an interactive mode or in a batch mode and is intended for experienced users with knowledge of computational dosimetry.

ICRP38 v. 1.0 (3/25/2003)
This package installs the nuclear decay data of ICRP Publication 38 and the three Windows-based codes. The code WinChain assembles the decay chain and provides guidance regarding the truncation of the chain. RadSum provide a brief summary of the emitted radiation for the user supplied radionuclides. The DexRax utility extracts from the master files, the decay data for user specified radionuclides.

DCFPAK v. 1.0 (3/29/2000)
The dose coefficient files and source code (FORTRAN) illustrating how to use the use the data files within an assessment code. This package is documented in ORNL/TM-13347. The dose coefficients for inhalation and ingestion intakes are those of ICRP Publication 30. The coefficients for external irradiation are from FGR-12. The download module, setup_DCF will install the files, source code, and executable. The code is a console application and hence runs under either DOS on Windows.

Software for efficiency transfer and true coincidence summing corrections
A gamma spectrometric laboratory has usually to be able to deal with many types of containers and filling heights. Calibrating for all these geometries requires a lot of resources. By the use of effiency transfer calibration obtained for one geometry can be transferred by numerical methods to a new one. The geometries should however be of a similar character if good quality results are to be expected (calibration for a point source should not be expected to be transferred accurately to a Marinelli beaker)
Truecoinc is a free Windows utility for calculating TCS corrections. It can be obtained by ordering a printed (comes with CD) copy of http://www-pub.iaea.org/MTCD/publications/PDF/te_1275_prn.pdf.

Efficiency transfer and coincidence summing corrections for gamma-ray spectrometry
This software is available free of charge. Currently it deals only with cylindrical geometries (which is sufficient for many users and covers at least some of the geometries for others).http://efftran.com/
Semiconductor detector efficiency calculations software
A commercial software which can also deal with more complex geometries, such as Marinelli beakers. The developers’ web site: http://www.dlabac.com/angle/
The software can interface directly with AMETEC/ORTEC’s GammaVision and is also distributed worldwide by the company.
GErmanium – SPectra – COrrection
A commercial software: “GESPECOR software has been developed initially for the computation of the self-attenuation corrections and of the coincidence-summing corrections useful in high resolution gamma ray spectroscopy. Later the computation of the full energy peak efficiency and of the total efficiency was added”.
For more information see: http://gespecor.de/en/
Efficiency Transfer for Nuclide Activity
ETNA is an application for conducting efficiency transfer operations and some coincidence summation correction.

A Novice experimenter interested in mainly Normally Occurring Radioactive Material (NORM)
Technologically Enhanced Radioactive Material (TENORM) to a lesser degree.
Chernobyl fascinates me to a fair degree, although I find the current Fukushima situation difficult to get reasoned scientific information amid media/internet waffle- some of which clearly is totally devoid of common sense or reason.
