Math & Numbers
Carrier-free specific activity from the half-life: A = ln2·N_A/T½ in Bq/mol and Ci/mmol, with optional Bq/g and Ci/g from molar mass.
Call this tool from your code in three languages.
curl -X POST 'http://127.0.0.1:3003/en/api/tools/specific-radioactivity' \
-H 'Content-Type: application/json' \
-d '{"halfLife":6.01,"halfLifeUnit":"hours","molarMass":99,"decimalPlaces":2}'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
POST http://127.0.0.1:3003/en/api/tools/specific-radioactivity| Name | Type | Required | Description |
|---|---|---|---|
| halfLife | number | Yes | Physical half-life in the selected time unit. Must be greater than zero. |
| halfLifeUnit | select | Yes | Time unit of the half-life. |
| molarMass | number | No | Molar mass of the radionuclide or labelled compound in g/mol; if provided, mass-based specific activity (Bq/g, Ci/g) is computed. |
| decimalPlaces | number | No | — |
