A web adaptation of the Professional Radioactive Decay Calculator developed by Md. Ahad Mia, Chittagong Medical College Hospital. Includes the supplied isotope presets, custom half-life, date-based physical decay, replacement-interval estimation and decay-only dose-rate correction. Evaluation release; not commissioned for clinical use.
Using this calculator
Select a supplied isotope preset or enter a custom half-life. Enter initial activity and use either reference/target dates or elapsed time with an explicit unit. Presets are copied from the supplied source, not independently certified. Date mode uses whole calendar days; elapsed-time mode supports shorter intervals. One year is 365.25 days. Activity stays in the selected input unit. Optional replacement threshold and initial dose rate add the corresponding original-app results. No daughter ingrowth or biological clearance is modelled.
