Radiation converters translate between different dose units (gray, sievert, rad, rem) and activity units (becquerel, curie).
공식
1 gray (Gy) = 1 joule/kg absorbed dose
- Gy
- 1 joule/kg absorbed dose — 1 joule/kg absorbed dose
단계별 가이드
- 11 gray (Gy) = 1 joule/kg absorbed dose
- 21 sievert (Sv) = gray × quality factor (accounts for radiation type)
- 31 becquerel (Bq) = 1 decay/second; 1 curie = 3.7 × 10¹⁰ Bq
풀어진 예시
입력
100 millirem (mrem) exposure
결과
1 millisievert (mSv) equivalent, annual background ~2-3 mSv
Safety threshold context
피해야 할 일반적인 실수
- ✕Confusing absorbed dose with effective dose (biological impact)
- ✕Neglecting duration in dose calculation
자주 묻는 질문
Why are there different dose units?
Absorbed dose (Gy) measures energy; equivalent dose (Sv) accounts for biological harm of different radiation types.
What are safe radiation levels?
Annual background ~3 mSv safe; occupational limits 20-50 mSv/year. Acute >1000 mSv causes acute radiation sickness.
