Radiation dose (toy)

Radiation dose (effective dose toy)

Numbers may vary by machine, route, and shielding. This is not dosimetry or occupational compliance advice. NASA / UNSCEAR publish flight and space ranges for education.

Flight hours / year μSv per flight hour (typ. ~3–7) Imaging (annual-ish use) NoneChest X-ray (~0.05 mSv each)Dental X-ray (~0.005 mSv)Mammogram (~0.4 mSv)CT head (~2 mSv)CT abdomen (~8 mSv)PET-CT (~14 mSv) Exams counted (per year) Space / high-altitude days / year μSv / day for those days (LEO order ~500–1000+ toy default) Occupational μSv / year (pilots, radiology staff, etc.) Years at that occupational rate Other annual μSv (background + lifestyle) Years to compound annual row (lifetime toy)

Annual row sum ≈ 3,250 μSv (~3.25 mSv)

Lifetime toy total ≈ 97,500 μSv (~97.5 mSv) = annual row × years

Career occupational-only sum (for reference): ≈ 0 μSv

Effective dose is a population risk tool, not individual prediction. NASA / UNSCEAR cite altitude and space exposure orders of magnitude; imaging values may vary by protocol.
