Description
A tritium luminous source combines radioactive decay with phosphor behavior.
A tritium luminous source combines radioactive decay with phosphor behavior.1
This model assumes unchanged phosphor efficiency and scales an independently measured starting brightness using the stored half-life convention.
When to use Tritium Vial Brightness Decay Calculator
Use this tool to apply the stated tritium vial brightness decay calculator operation with an explicit input and unit basis.
How to use Tritium Vial Brightness Decay Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualIndependentlyMeasuredInitialTritiumBrightness, actualElapsedYears and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualIndependentlyMeasuredInitialTritiumBrightness | Initial tritium brightness, on the basis specified in the algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
| actualElapsedYears | Elapsed years, on the basis specified in the algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
Require nonnegative initial brightness and elapsed years. Multiply initial brightness by two raised to minus years divided by 12.32; retain the initial brightness unit.
conditional brightness = initial × 2^(−years/12.32) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Modeled brightness in the initial brightness unit. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.
