☢️ Astronaut Radiation Dose Ledger

☢️ Astronaut Radiation Dose Ledger

Combine prior dose, mission duration, a measured or assumed daily rate, shielding reduction and one-off events. Compare the total with a value you choose without pretending that one universal career limit exists.

Educational bookkeeping only. Dose rate and shielding response depend on spectrum, geometry, tissue and detector; agency limits are individual and programme-specific. The background comparison uses the worldwide average natural exposure of about 2.4 mSv/year only as scale.
