## What is radioactivity and its units?

Radioactivity is a measure of the rate at which a radioactive substance undergoes radioactive decay, releasing radiation in the process. There are several units used to quantify radioactivity, including

**Becquerel (Bq):**The becquerel is the SI unit of radioactivity. It represents one decay event per second. It is named after Henri Becquerel, the French physicist who discovered radioactivity.**Curie (Ci):**The curie is a non-SI unit of radioactivity. It is approximately equal to 3.7 x 10^10 becquerels, representing the activity of one gram of radium-226. The Curie is named after Marie Curie, the renowned physicist, and chemist who conducted pioneering research on radioactivity.**Rutherford (rd):**The Rutherford is another non-SI unit of radioactivity. It is equal to 1 million becquerels (1 x 10^6 Bq) and is often used in nuclear physics and related fields. Rutherford is named after Ernest Rutherford, a prominent physicist who made significant contributions to the understanding of atomic structure and radioactivity.

Here is a table summarizing the conversions between these units:

Unit | Equivalent |

1 Bq | 2.7 x 10^-11 Ci |

1 Bq | 1 x 10^-6 rd |

1 Ci | 3.7 x 10^10 Bq |

1 Ci | 3.7 x 10^4 rd |

1 rd | 1 x 10^6 Bq |

1 rd | 2.7 x 10^-5 Ci |

Please note that the values provided are approximations and are commonly used for practical purposes.

## How to convert units of radioactivity?

Let's go through the process of converting between different units of radioactivity using a solved example.

Example: Convert 500 becquerels (Bq) to curies (Ci).

To convert from becquerels to curies, we'll use the conversion factor: 1 Ci = 3.7 x 10^10 Bq.

**Step 1:** Set up the conversion factor.

1 Ci = 3.7 x 10^10 Bq

**Step 2:** Plug in the given value and solve.

Given: 500 Bq

To convert Bq to Ci, we'll use the conversion factor as a fraction, with Bq in the denominator and Ci in the numerator.

(500 Bq) x (1 Ci / 3.7 x 10^10 Bq) = (500 / 3.7 x 10^10) Ci

**Step 3:** Calculate the result.

(500 / 3.7 x 10^10) Ci ≈ 1.35 x 10^-11 Ci

Therefore, 500 becquerels is approximately equal to 1.35 x 10^-11 curies.

Remember to adjust the significant figures and round the final answer appropriately based on the given values and the level of precision required.

**Note: **The example above is for illustrative purposes, and actual conversion calculations may vary based on the specific conversion factors and values involved. This is why, the radioactivity converter is recommended.
