What is the formula for radioactivity?
The SI unit of radioactivity is becquerel (Bq) and this term is named after Henri Becquerel. Unit of radioactivity is defined as: The activity of a quantity of radioactive material where one decay takes place per second. 1 becquerel = 1 radioactive decay per second = 2.703×10 -11 Ci. Other Radioactivity Units:
- What is radioactivity?Radioactivity refers to the amount of ionizing radiation released by a material.
- What was the older unit to measure the amount of radioactivity?The unit for measuring the amount of radioactivity was the curie (Ci).
- What is the term used to measure the magnitude of radiation exposures?The magnitude of radiation exposures is measured in the terms of radiation dose.
- Define 1 curie1 curie = 3.7×10 10 radioactive decay per second.
The becquerel (/ ˌ b ɛ k ə ˈ r ɛ l /; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as an activity of one decay per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used.
One curie (1 Ci) is equal to 3.7 × 10 10 radioactive decays per second, which is roughly the amount of decays that occur in 1 gram of radium per second and is 3.7 × 10 10 becquerels (Bq). In 1975 the becquerel replaced the curie as the official radiation unit in the International System of Units (SI).

The International System of Units, internationally known by the abbreviation SI (from French Système international d'unités ), is the modern form of the metric system and the world's most widely used system of measurement. Coordinated by the International Bureau of Weights and Measures (abbreviated BIPM from French: Bureau international des ...
Radiation activity is measured in an international (SI) unit called a becquerel (Bq). The becquerel counts how many particles or photons (in the case of wave radiation) are emitted per second by a source.
The International System of Units (SI) unit of radioactive activity is the becquerel (Bq), named in honor of the scientist Henri Becquerel. One Bq is defined as one transformation (or decay or disintegration) per second.
Apr 24, 2024 · The units of radioactivity measure the rate at which radioactive decays occur in a sample of radioactive material. The primary unit used is the becquerel (Bq), defined as one decay per second. This unit is part of the International System of Units (SI) and was named after Henri Becquerel, one of the discoverers of radioactivity.
