Frequently Asked Questions
-
What does one millicurie represent?
-
One millicurie equals one thousandth of a curie and quantifies radioactive decay rate at roughly 3.7×10^7 disintegrations per second.
-
When should I use nanocurie units?
-
Nanocurie units are suitable for reporting very low radioactive activity levels such as environmental contamination or small biochemical tracer quantities.
-
How do I convert millicurie to nanocurie?
-
Multiply the value in millicurie by 1,000,000 to get the equivalent value in nanocurie.
Key Terminology
-
Millicurie [mCi]
-
A unit of radioactive activity equal to one thousandth of a curie, representing the rate of 3.7×10^7 nuclear decays per second.
-
Nanocurie [nCi]
-
A unit of radioactive activity equal to 10^-9 curie, used for low-level activity measurement and equal to 37 disintegrations per second.
-
Radioactive Activity
-
The rate at which a radioactive material undergoes nuclear decay, measured in units like curie, millicurie, or nanocurie.
