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.
