About

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.

Highlights
  • 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.

Always seek a doctor’s advice in addition to using this app and before making any medical decisions. Decay Calculator Includes nearly every radiopharmaceutical you might encounter in nuclear medicine. Radiation Dose to patients Based on ICRP 128, calculations are done for a variety of tracers, uptake mechanisms and age groups EANM Dose card Pediatric dose calculations CT dose From the scanner we find DLP and can convert that to Effective dose. We have ICRP publication 102, but also the work of Inoue et al that looked at the most normal scan range in PET: whole body. They suggest k-factors for that scan range. Activity dose-rate and reversed Dose-rate Activity What is safe distance from a source? Or how much activity is in the spill on the floor? And other use-cases. Inventory Maintain a list of QC isotopes used to calibrate equipment in nuclear medicine. Track your inventory and monitor decay over time. Export/import to share with colleagues Logging Create a log entry of calulations and find them here. Export/import for easy distribution or safe keeping. Settings Customize date and time formats, select activity units (MBq or mCi), and choose between metric and imperial measurements.

Verdict

The call

The clearest difference is in-app purchases: ICCR at none against Nuclear Med Suite's 1. ICCR also leads on ads (none vs shown) and iOS requirement (15.6 vs 18.2). Nuclear Med Suite's advantage is update cadence (every 5 days vs every 33 months). On price and device support there is nothing between them.
