Radiation activity is a crucial concept in the field of nuclear physics and radiology. It refers to the rate at which a radioactive substance undergoes radioactive decay, emitting radiation in the process.

To better comprehend and work with radiation activity, we have developed this robust converter tool to facilitate the seamless conversion between different units of radiation activity, ensuring accuracy and precision in scientific measurements.

• Becquerel (Bq): The becquerel is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used.

• Kilobecquerel (kBq): `1 kBq = 10^3 Bq` (1,000 Bq)

• Megabecquerel (MBq): `1 MBq = 10^6 Bq` (1,000,000 Bq)

• Gigabecquerel (GBq): `1 GBq = 10^9 Bq` (1,000,000,000 Bq)

• Terabecquerel (TBq): `1 TBq = 10^12 Bq` (1,000,000,000,000 Bq)

• Millibecquerel (mBq): `1 mBq = 10^(-3) Bq` (0.001 Bq)

• Curie (Ci): The curie is a unit of radioactivity, representing 3.7 10^10 disintegrations per second, or `1 Ci = 3.7 10^10 Bq` (37,000,000,000 Bq).

• Kilocurie (kCi): `1 kCi = 10^3 Ci = 3.7 * 10^13 Bq` (37,000,000,000,000 Bq).

• Millicurie (mCi): `1 mCi = 10^(-3) Ci = 3.7 * 10^7 Bq` (37,000,000 Bq).

• Microcurie (μCi): `1 μCi = 10^(-6) Ci = 3.7 * 10^4 Bq` (37,000 Bq).

• Nanocurie (nCi): `1 nCi = 10^(-9) Ci = 3.7 * 10^1 Bq` (37 Bq).

• Picocurie (pCi): `1 pCi = 10^(-12) Ci = 3.7 * 10^(-2) Bq` (0.037 Bq).

• Rutherford (rd): The rutherford is a unit of radioactivity, representing one million nuclei decay per second, or `1 rd = 1,000,000 Bq`.

• One/second (1/s): This is an equivalent to the Becquerel, representing one decay per second.

• Disintegrations/second: The number of radioactive disintegrations occurring in one second. This is also an equivalent to the Becquerel.

• Disintegrations/minute: This is the number of radioactive disintegrations occurring in one minute and is equal to `1/60 Bq`.

Understanding and accurately measuring radiation activity are vital in various scientific and medical applications. This Radiation Activity, or Radioactive Decay Converter tool provides a convenient means to convert between different units, ensuring consistency and precision in the interpretation of radiological data. Whether working with terabecquerels in nuclear physics or microcuries in medical diagnostics, this tool is an invaluable resource in the study and application of radiation activity.
