## What is radioactivity and its units?

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:

## 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.
