Dose & Dose Rate
Every dose & dose rate calculator on CalcEngines — each with its formula, a worked example, the standard it follows and the assumptions it makes.
4 calculators in this section
- CT Dose: DLP to Effective Dose CalculatorEffective dose from the dose-length product, computed at three published coefficient sets at once — because for the chest they disagree by 71 per cent, the reason is which generation of ICRP tissue weighting factors each was computed with, and almost nobody says which they are using.
- Fluoroscopy Skin Dose CalculatorPeak skin dose from the cumulative air kerma at the reference point, cross-checked against the kerma-area product route — with all four multipliers editable, their published ranges stated, and the published injury thresholds beside the answer for comparison rather than as a verdict.
- Gamma Dose Rate Point Source CalculatorThe dose rate from a point gamma source, with the air kerma rate constant printed as the published range it really is, the first-principles derivation beside it, optional narrow-beam shielding, and the inverse solved — the distance at which the rate falls to a figure you name.
- Nuclear Medicine Administered Activity CalculatorAdministered activity scaled from a reference activity you supply, by eight methods side by side — because the published paediatric cards scale sublinearly in body weight, and a per-kilogram activity borrowed from an adult under-doses a 3 kg neonate by a factor approaching four.
