ICCR vs RadSafePro
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
ICCR
This reference tool provides information on internal contamination with radionuclides and their medical countermeasures. It estimates reference concentrations in urine based on hypothetical patient scenarios and standard biokinetic models. The app is designed for professionals interested in radioactive material contamination and therapy.
- Radionuclide and medical countermeasure reference information
- Hypothetical patient scenario assessments
- Reference concentration estimation in urine
- Save, edit, and share assessments
- Information on internal contamination and therapy

The Internal Contamination Clinical Reference app is a reference tool to be used for educational and informational purposes only. The app provides information about internal contamination with a number of radionuclides and their medical countermeasure. The app estimates reference concentrations of radionuclides in urine using standard biokinetics models and assuming intakes equal to one Clinical Decision Guide (CDG) for each radionuclide based on hypothetical patient scenarios. The intended audience for the app is clinicians, health physicists, radiation safety officers, medical and public health laboratory scientists, or any other professional interested in internal contamination with radioactive materials and their medical therapy. Some basic understanding of concepts behind internal contamination and internal dosimetry are required to fully benefit from this application. The Internal Contamination Clinical Reference app features: * Reference information on a particular radionuclide or a medical countermeasure * Users can perform assessments based on hypothetical patient scenarios with each assessment projecting a reference concentration of radionuclides in urine based on user input * The assessment can be saved, edited and shared For more information, please visit http://www.cdc.gov/nceh/radiation/ or email rsbinfo@cdc.gov. This app was developed and produced by the Centers for Disease Control and Prevention http://www.cdc.gov/ and Oak Ridge Institute for Science and Education (ORISE) http://www.orau.gov/orise.htm through an interagency agreement with the U.S. Department of Energy (DOE). ORISE is managed by Oak Ridge Associated Universities under DOE contract number DE-AC05-06OR23100.

With over 1100 isotopes, the following can be done: 1. Calculating the decayed activity with different units (mCi or Bq). 2. See the decay chart: - In the chart, it is easy to find out all decay points by simply tapping on the graph. - The graph can be redrawn with the desired activity (input) and units. - Snapshot can be taken and saved to camera-roll directly. 3. Estimating the dose rate from each isotope (as a point source only and < 2 MV) at different distances with (mCi or MBq) and (meter or feet) units. Optionally, shielding can be incorporated in the calculations as well. 4. Inverse Square Law is introduced. 5. Look up for detailed information through wikipedia. To simply deal with such huge list of isotopes, all isotopes tables are equipped with reliable search engines to filter for the wanted isotope. With a user friendly radiation units convertor, it is easy to convert between radiation units like exposure, absorbed and equivalent doses. For more convenience a calculator keyboard was adopted to replace the normal keyboard in order to complete simple mathematical operations The App is built with tap gesture (swipe right) ability to get back to the previous pages.

Verdict
The clearest difference is price: ICCR at Free against RadSafePro's $2.99. ICCR also leads on rating (5.0 vs 4.7). RadSafePro's advantage is update cadence (every 2 months vs every 33 months) and ratings volume (42 vs 2). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
ICCR is free to download; RadSafePro costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
ICCR holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: RadSafePro has 42 ratings behind it against 2, so its average is the more settled of the two.
ICCR ships an update every 33 months, RadSafePro every 2 months. The most recent releases landed on October 13, 2026 and October 18, 2026 respectively.
