InterSpec assists in analyzing spectral nuclear radiation data, using a peak-based methodology. Common uses include identifying nuclides present, determining source activity, shielding amounts, source age, or other nuclear reactions present. InterSpec also provides a number of other tools useful for analyzing radiation data including spectral file format converting, dose rate calculations, interactive nuclide decay and reference information, gamma cross section calculations and references, and more. InterSpec can open data files from most common spectral radiation detectors (e.g., most NaI, HPGe, LaBr, CLYC, CsI, etc. based systems) and assist in their analysis.

Verdict

The call

The clearest difference is rating: RDS at 5.0 against InterSpec Radiation Analysis's 4.3. RDS also leads on update cadence (every 3 months vs every 11 months). InterSpec Radiation Analysis's advantage is ratings volume (12 vs 1) and iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.
