Geology Electron Spin Resonance Age Calculator
electron-spin resonance actual equivalent-dose/dose-rate age under independently resolved fading, uptake, water and saturation assumptions. Actual independently matched quantities/units required; not infer causal effect, clinical guidance or safe design.
Description
Electron-spin-resonance age relates equivalent dose to an applicable average dose rate.
Electron-spin-resonance age relates equivalent dose to an applicable average dose rate.1
Signal interpretation and dose history precede the ratio. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Geology Electron Spin Resonance Age Calculator
Use this tool to calculate the stated observation or conditional model from supplied measurements. Establish the sample and coordinate basis, matching units, calibration source and applicable model assumptions.
How to use Geology Electron Spin Resonance Age Calculator and understand its results
- Establish the sample and coordinate basis, matching units, calibration source and applicable model assumptions.
- Enter actualIndependentlyResolvedEquivalentDoseGy, callerIndependentlyMatchedAverageDoseRateGyPerYear, using the field meanings and rules below, then run the tool.
- Read result.observedRatio. Interpret each field using the units, signs and evidence rules below.
- If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualIndependentlyResolvedEquivalentDoseGy | Actual independently resolved equivalent dose gy | number | Required |
| callerIndependentlyMatchedAverageDoseRateGyPerYear | Caller independently matched average dose rate gy per year | number | Required |
Require nonnegative actualIndependentlyResolvedEquivalentDoseGy and positive callerIndependentlyMatchedAverageDoseRateGyPerYear. Divide numerator by denominator without percent scaling. Values need not be integers and the tool does not require numerator≤denominator or clamp the result. Establish matching measurement scope and units independently. Equivalent dose is in grays and average dose rate in grays per year, so the ratio returns conditional years.
result=1×actualIndependentlyResolvedEquivalentDoseGy/callerIndependentlyMatchedAverageDoseRateGyPerYear Apply the field units and exact ordering, boundary and evidence rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result containing the calculation or selected reference fields below | object |
| result.observedRatio | Conditional duration in years on the matched dose or concentration basis | number |

}Limitations and assumptions
Signal interpretation and dose history precede the ratio. Results depend on the independently established measurement basis and the exact model assumptions above.
Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.
Alternative or Complementary methods
Use Geology Thermoluminescence Age Calculator to examine a related aspect: Thermoluminescence age relates equivalent dose to an applicable time-averaged dose rate.
Use Geology Cosmogenic Helium 3 Age Calculator where its separate inputs and scope apply: Stable cosmogenic helium-3 accumulation can be related to a matched production rate under adopted exposure assumptions.
