How this service works
Radioactive decay calculator from initial amount, half-life and elapsed time - remaining amount and decay constant
Output
Returns a JSON object with the initial amount, half-life, elapsed time, unit, number of half-lives elapsed, remaining amount, decayed amount, remaining percentage, remaining fraction, decay constant per unit, mean lifetime, and the mathematical formula used for the calculation, along with a scope note explaining coverage and limitations.
Example use cases
Carbon dating age estimation
“I have a sample that started with 200 grams of Carbon-14 and its half-life is 5730 years — how much would be left after 11460 years, and what fraction has decayed? Use years as the unit.”
Medical isotope dosage tracking
“A patient received 50 milligrams of Iodine-131 which has a half-life of 8 days. How much of it remains in their body after 24 days? Show me the remaining amount and percentage in days.”
Nuclear waste storage planning
“We have 10000 kilograms of Cesium-137 with a half-life of 30 years. How much will remain after 300 years, and what's the decay constant per year?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/radiation/decay?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, formula-based radioactive decay calculation with full output including decay constant, mean lifetime, and remaining fraction — especially useful in scientific, educational, nuclear medicine, or environmental modeling contexts where all decay parameters are known and a structured JSON result with the underlying formula is needed.
Side effects
- Missing required query parameters (initial, half_life, elapsed, unit) returns an error
- Non-numeric or zero/negative values for initial or half_life cause validation failure
- Negative elapsed time is rejected
- Extremely large or small numbers may cause precision issues
- Invalid or overly long unit strings may be rejected
- Payment failure returns 402 status requiring x402 protocol payment
