What Is This Tool?
This tool converts radiation activity values from disintegrations per second, the SI unit of radioactive decay, to picocurie (pCi), a unit often used in environmental and health risk assessments for low-level radioactivity.
How to Use This Tool?
-
Enter the radiation activity value in disintegrations per second (Bq)
-
Select picocurie [pCi] as the target unit
-
Click the convert button to see the equivalent value in pCi
-
Use the converted output for environmental or medical radioactivity assessments
Key Features
-
Converts activity units from disintegrations/second to picocurie with a fixed conversion rate
-
Browser-based and easy to use with clear input and output fields
-
Supports applications in environmental monitoring, nuclear medicine, and lab measurements
-
Displays results suitable for reporting low-level radioactive contamination and radon exposure
Examples
-
5 disintegrations/second equals 135.14 picocurie [pCi]
-
0.1 disintegrations/second equals 2.70 picocurie [pCi]
Common Use Cases
-
Reporting indoor radon concentration in air as pCi/L for health assessments
-
Measuring low-level radioactivity in drinking water and environmental samples
-
Quantifying administered activities in nuclear medicine and radiopharmaceuticals
-
Calibrating radiation detectors and characterizing radioactive waste
Tips & Best Practices
-
Double-check sample conditions and instrumentation calibration before conversion
-
Use this tool for approximate conversions aligning with environmental and health standards
-
Refer to correct units to ensure communication clarity when reporting results
Limitations
-
The conversion is approximate since picocurie is derived from the non-SI unit curie
-
Measurement precision may vary, especially at very low activity levels
-
Calibration differences across instruments can affect the accuracy of converted values
Frequently Asked Questions
-
What does disintegrations per second measure?
-
It measures the activity of a radioactive sample by counting the number of nuclear decays occurring each second and is equivalent to one becquerel.
-
Why convert disintegrations per second to picocurie?
-
Because picocurie is commonly used in environmental health assessments and for reporting low-level radioactive contamination.
-
Is the conversion exact between these units?
-
No, the conversion is approximate due to picocurie being based on the curie, a non-SI unit.
Key Terminology
-
Disintegrations/second
-
A measure of radioactive activity equal to the number of nuclear decays occurring each second; identical to one becquerel (Bq).
-
Picocurie [pCi]
-
A unit of radioactive activity equal to 10⁻¹² curies, commonly used for expressing low-level radioactivity like indoor radon and environmental samples.
