Que es el/la difference entre Gray y Sievert?

Gray measures absorbed energy (joules/kg). Sievert adjusts for biological effectiveness—alpha radiation causes mas damage per Gray than gamma. 1 Gy of alpha radiation es igual un/una ~20 Sv, while 1 Gy of gamma es igual un/una 1 Sv.

Radiation Units Explained

Measuring Radiation

Learn Units

Radiation es medido in several maneras: source activity, absorbed energy, y biological effect. Different unidades serve diferente purposes in radiation protection.

Unidad Comparison

SI Unidad	Old Unidad	Measures
Becquerel (Bq)	Curie (Ci)	Activity
Gray (Gy)	Rad	Absorbed dose
Sievert (Sv)	Rem	Effective dose

Conversions: 1 Gy = 100 rad; 1 Sv = 100 rem

Conclusion

Becquerels medir source activity; Grays medir energy deposited; Sieverts account for biological effect. For radiation protection, el/la Sievert es la mayoria relevant as eso reflects real health risk desde diferente radiation types.
