单位换算

Curies 和 d . p . m 的换算.
1 Curie (Ci) =2.22×10¹² d . p . m .
1 milliCurie (mCi) =2.22×10⁹ d . p . m .
1 microCurie (m Ci) =2.22×10⁶ d . p . m .
1 nanoCurie (nCi) = 2.22×10³ d . p . m .
1 picoCurie (pCi) =2.22 d . p . m .

Curies 和 Becquerels的换算
1 Ci = 3.7×10¹⁰ Bq =37GBq (gigaBq)
1 mCi = 3.7×10 ⁷ Bq =37MBq (megaBq)
1 m Ci = 3.7×10 ⁴ Bq =37kBq (kiloBq)
1 GBq =2.7×10 ^-4 Ci =27.027mCi(milliCi)
1 MBq =2.7×10 ^-7 Ci =27.027m Ci(nanoCi)
1 kBq =2.7×10-¹⁰ Ci =27.027nCi (nanoCi)
