What Is This Tool?
This unit converter allows you to convert values of radioactive activity from picocurie (pCi), a very small measure of radioactivity, to nanocurie (nCi), a larger unit used for similar radiation measurements. The tool supports accurate unit translation to aid in environmental, laboratory, and health physics applications.
How to Use This Tool?
-
Enter the value in picocurie (pCi) you wish to convert
-
Select picocurie [pCi] as the from unit and nanocurie [nCi] as the to unit
-
Click the convert button to calculate the corresponding nanocurie value
-
Review the result for analysis or reporting purposes
Key Features
-
Converts radioactive activity from picocurie (pCi) to nanocurie (nCi)
-
Based on the standard conversion: 1 pCi equals 0.001 nCi
-
Supports use cases in environmental monitoring and radiological laboratories
-
Easy-to-use, browser-based interface for quick conversions
-
Useful for interpreting low-level radiation data and calibration sources
Examples
-
Converting 500 pCi results in 0.5 nCi
-
Converting 1000 pCi results in 1 nCi
Common Use Cases
-
Reporting indoor radon levels and low-level radioactivity in air and water samples
-
Measuring small contamination levels in environmental and radiological monitoring
-
Calibrating instrumentation and checking activity of laboratory radioactive sources
-
Quantifying radiolabeled tracers in biochemical assays and diagnostic preparations
Tips & Best Practices
-
Ensure input values are within the measurable range to avoid detection limit errors
-
Use this converter to express data in units convenient for reporting and regulatory compliance
-
Verify unit selections carefully to maintain conversion accuracy
-
Cross-check results when working near measurement precision thresholds
Limitations
-
Conversion is based on the standard curie definition and does not reflect individual isotope decay schemes
-
Picocurie units represent very low radioactivity and may be close to instrument detection limits
-
Care is required when interpreting values near the precision limits to prevent misreporting

Key Terminology
-
Picocurie (pCi)
-
A unit of radioactive activity equal to 10⁻¹² curies, commonly used to measure very low radioactivity such as indoor radon or water contamination.
-
Nanocurie (nCi)
-
A unit of radioactive activity equal to 10⁻⁹ curies, used for low-level activity sources and calibration in radiological and biochemical applications.
-
Curie (Ci)
-
A standard unit of radioactive activity defined as 3.7×10¹⁰ disintegrations per second.
