What is the half-life of promethium-147?

  1. 1.54 years

  2. 2.64 years

  3. 3.57 years

  4. 4.20 years

The correct answer is: 2.64 years

Promethium-147 has a well-documented half-life of approximately 2.64 years. This means that in a span of 2.64 years, half of a given quantity of promethium-147 will decay into other isotopes or elements. The half-life is a critical concept in radiation safety as it helps to understand the duration of radioactivity and the decay process of radioactive materials. Knowing the half-life allows for effective planning and management when handling materials that emit radiation, including considerations for storage, disposal, and safety measures in environments where such materials are present. Understanding the specific characteristics of promethium-147 is essential for professionals working in fields that involve radioactive substances.
