Radiazione
Informazioni Radiation Unita Conversione
Radiation misurazione involves several related but distinct quantities: activity (how much radioactive decay—disintegrations per secondo), absorbed dose (energy deposited in tissue—joule per chilogrammo), e equivalent dose (biological effect accounting per radiation type). Each quantity ha its own units, e confusing them e un common error. Activity tells you circa il source; dose tells you circa il effect on tissue.
Il SI units sono becquerel (Bq) per activity, gray (Gy) per absorbed dose, e sievert (Sv) per equivalent dose. Older units (curie, rad, rem) remain in widespread usare, especially in il United States e in older literature. Knowing both SI e traditional units e essential per interpreting safety documentation, medical records, e regulatory requirements across different countries e eras.
Our converter handles all standard radiation misurazione units per activity, dose, e exposure.

Radiation Unita Riferimento
Becquerel (Bq) – Il SI unit di radioactivity, named after Henri Becquerel. 1 Bq = 1 nuclear decay per secondo. Activity measures source strength—un high-Bq source undergoes many decays but puo pose low risk if emissions sono weak o well-shielded. Comuni multiples: kBq, MBq, GBq.
Curie (Ci) – Historical activity unit, originally il activity di 1 grammo di radium-226. 1 Ci = 3.7 × 10¹⁰ Bq = 37 GBq esattamente. Named after Marie e Pierre Curie. Still standard in US medical isotopes (mCi) e industrial radiography. Comuni multiples: pCi, nCi, μCi, mCi.
Gray (Gy) – Il SI unit di absorbed dose, measuring energy deposited per unit mass. 1 Gy = 1 J/kg. Named after Louis Harold Gray. Il gray applies un any material—same energy deposition puo hanno different biological effects depending on radiation type. Diagnostic procedures: μGy un mGy; radiation therapy: Gy.
Rad – Traditional absorbed dose unit. 1 rad = 0.01 Gy = 100 erg/g. Il name stands per "Radiation Absorbed Dose." Still encountered in older US regulations, historical documents, e some industrial contexts.
Sievert (Sv) – Il SI unit di equivalent e effective dose, accounting per radiation type via weighting factors. 1 Sv = 1 Gy × radiation weighting factor (wR): 1 per X-rays/gamma, 20 per alpha particles. Named after Rolf Sievert. Il practical unit per radiation protection e safety limits.
Rem – Traditional equivalent dose unit. 1 rem = 0.01 Sv = 10 mSv. "Roentgen Equivalent Man." Comuni in US nuclear industry dose records. Occupational limits sono often expressed in rem/anno alongside Sv equivalents.
