What is a Radiation-Activity Converter?
A radiation activity converter is a tool that converts between units of radioactive decay rate such as becquerel, curie, millicurie, and disintegrations per second. It is essential for nuclear medicine, radiation safety, and health physics applications.
How to Convert Radiation-Activity Units
Select the activity unit you want to convert from and the target unit using the dropdown menus. Enter your value in the input field and the converter instantly calculates the equivalent activity. Most commonly used for becquerel-to-curie conversions in nuclear medicine.
Radiation-Activity Conversion Formulas
History of Radiation-Activity Measurement
The becquerel is named after Henri Becquerel, who discovered radioactivity in 1896. One becquerel equals one nuclear disintegration per second. The curie, named after Marie and Pierre Curie, was originally defined as the activity of one gram of radium-226 (approximately 3.7 × 10¹⁰ Bq).
About This Radiation-Activity Converter
This radiation activity converter supports 13 units including becquerel, curie, millicurie, microcurie, nanocurie, picocurie, kilobecquerel, megabecquerel, gigabecquerel, terabecquerel, rutherford, disintegrations/second, and disintegrations/minute.
Frequently Asked Questions
How do I convert curie to becquerel?
Multiply the curie value by 3.7 × 10¹⁰ to get becquerel. For example, 1 mCi = 0.001 Ci × 3.7 × 10¹⁰ = 37,000,000 Bq = 37 MBq.
What is the difference between becquerel and curie?
Both measure radioactive decay rate. Becquerel is the SI unit (1 disintegration/second). Curie is the older unit (3.7 × 10¹⁰ disintegrations/second). The curie is much larger than the becquerel.
What is a picocurie?
A picocurie (pCi) equals 10⁻¹² curie or 0.037 becquerel. It is commonly used for measuring radon levels in homes. The EPA action level for radon is 4 pCi/L of air.
How do I convert becquerel to millicurie?
Divide the becquerel value by 37,000,000 to get millicurie. For example, 185,000,000 Bq ÷ 37,000,000 = 5 mCi.
What is a rutherford?
A rutherford (Rd) equals 1,000,000 disintegrations per second, which is the same as 1 megabecquerel (MBq). It was proposed as a unit but never widely adopted.
