Radiation Environment Calculator
Estimate the radiation environment for your orbit. Compute total ionizing dose, single event upset rates, and shielding requirements for spacecraft electronics.
What It Does
The Radiation Environment Calculator estimates the space radiation environment for a given orbit. Input your orbit altitude, inclination, and mission duration to get estimates of trapped proton and electron fluences, total ionizing dose (TID) behind various shielding thicknesses, and single event effect (SEE) rate estimates. The tool uses standard radiation belt models to provide design-level estimates.
Key Features
- Trapped proton and electron flux estimates for arbitrary orbits
- Total ionizing dose vs shielding thickness curves
- Solar particle event contribution for mission duration
- Comparison against common electronics radiation tolerance levels
Why It Matters
Radiation drives electronics selection, shielding mass, and mission lifetime for any orbit that intersects the Van Allen belts. A spacecraft in MEO or GTO can accumulate more radiation in months than a LEO satellite sees in its entire mission. Understanding the radiation environment early lets you select radiation-tolerant parts during preliminary design rather than discovering at CDR that your COTS electronics will not survive the mission.
