Convert Nanobecquerels to Curies
Convert Nanobecquerels (nBq) to Curies (Ci) instantly and accurately.
Conversion Formula
Ci = nBq × 2.702702703e-20
About Nanobecquerels
The nanobecquerel (nBq) equals 10⁻⁹ Bq. Atmospheric surveillance for tritium and ¹⁴C near nuclear facilities reports discharge rates in nBq/m³; EU drinking water directives set indicator activity concentrations for some radionuclides at the nBq/L level. 1 nBq = 10⁻⁹ Bq = 10⁻³ µBq.
About Curies
The curie (Ci) equals exactly 3.7 × 10¹⁰ Bq = 37 GBq, originally defined as the activity of 1 g of ²²⁶Ra. Still widely used in the US: ⁶⁰Co teletherapy sources are 5000-15000 Ci; ¹³⁷Cs blood irradiators are 1000-40000 Ci; NRC source licences for industrial radiography cite Ci limits. 1 Ci = 3.7 × 10¹⁰ Bq.
