Mostly free online or downloadable software in alphabetical order.

AcuteDose Code 1.2.  The AcuteDose code computes age-specific absorbed dose coefficients for user specified commitment periods (integration times post an acute intake) and radionuclides for inhalation and ingestion intakes of radionuclides. The upper limits for the integrals are read from \DATA\AcutDose.INI.  The absorbed dose rate files were archived on the FGR-13 CD (Contact EPA for CD).  The user selects,

  1. either the ingestion or inhalation data set,
  2. the age(s) of interest and
  3. the organ(s) to be processed.

To select multiple ages or organs mark the desired items by holding down and clicking the left mouse button. When prompted, the user should enter the radioisotope of interest.

Interactive RadioEpidemiological Program (IREP)

NIOSH-IREP, Version 5.8. NIOSH-IREP was created for use by the Department of Labor for adjudication of claims in accordance with the Energy Employees' Occupational Illness Compensation Program Act of 2000 (EEOICPA). NIOSH-IREP was adapted from the National Institutes of Health's (NIH) Interactive RadioEpidemiological Program (IREP) developed by the National Cancer Institute (NCI) to update the NIH Radioepidemiological Tables of 1985. (The version of IREP developed by NCI is known as NIH-IREP. See below).  General background information on NIOSH-IREP.

NIH-IREP, Version 5.6.1. The Interactive RadioEpidemiological Program (IREP) was developed as part of the effort to update the 1985 Radioepidemiological Tables report. The 1985 report was mandated by the 1983 "Orphan Drug Act" (PL 97-414) which instructs to "devise and publish radioepidemiological tables that estimate the likelihood that persons who have or have had any of the radiation-related cancers and who have received specific doses prior to the onset of such disease developed cancer as a result of these doses." NIH-IREP contains a collection of risk coefficients for cancer incidence obtained mainly from the Japanese A-bomb survivors study, but also from other epidemiological studies. The risk coefficients are adjusted for random and systematic errors in the A-bomb survivors dosimetry, and they are adapted for the U.S. population. Appropriate adjustments of the coefficients are made for low dose and low dose-rate exposure situations. The uncertainties in every component are fully expressed and propagated.

Radar Software.  Variety of free and commercial nuclear medicine software.

Online Medical Dose Calculator.  This form gives radiation dose estimates for certain radiographic and nuclear medicine procedures, based on literature reported values. Individual organ doses and total body effective doses are given for these specified examinations, and some combinations of examinations. In addition, a short statement is generated, which may be useful as part of a patient consent form document, explaining the radiation doses as numerical values and as equivalent days of exposure to natural background radiation.

MIRDOSE and OLINDA/EXM.  The MIRDOSE software has been popular for a number of years for calculating internal radiation dose estimates for radionuclides used in nuclear medicine.  The program has phantom libraries which permit the calculation of these doses for individuals of different age and size and for women at different stages of pregnancy.  The code OLINDA/EXM, which is an acronym standing for Organ Level INternal Dose Assessment/EXponential Modeling, was designed as an update to MIRDOSE. 

Visual Monte Carlo (VMC).  VMC is a computer program that simulates the irradiation of the human body by external sources. It uses a voxel phantom produced at Yale University and the Monte Carlo technique to simulate the emission of photons by a point, ground, cloud source or X ray source.  It then transports the photons through the human body phantom and calculates the dose to each body region.

VARSKIN.  VARSKIN Mod 2 calculates the radiation dose (gamma and beta) to skin from radioactive contamination of skin or protective clothing. 

Dynamic Bladder Model (MIRD Pamphlet 14).  The MIRD Committee developed an analysis of how urinary bladder dose changes for a number of radiopharmaceuticals as a function of initial bladder volume, urine flow rates, and bladder voiding schedule.

To remove RiskTab from the computer click the executable UNINS000.EXE in the in the folder to which RiskTab was installed.

RiskTab tabulates the lifetime risk per unit intake by inhalation or ingestion for a user specific radionuclide and period of chronic intake. The tabulations are derived from risk as a function of age files archived on the FGR 13 CD (Contact EPA for CD). The CD files have been converted to direct access files to facilitate RiskTab access to the data for the user specified radionuclide. Age and gender specific intakes for the intake period are calculated assuming a uniform concentration of the radionuclide in air and water (and in the diet). The risk coefficients for the intake are per Bq inhaled or ingested over the exposure period.  November 2012.
