What is the half-life of Plutonium 239?

The half-life of Plutonium-239 is identified as 24,100 years, which is widely accepted in the scientific literature. This value indicates the time it takes for half of a sample of Plutonium-239 to decay into other elements. Understanding the half-life is crucial for professionals in the field of radiation protection, as it helps in managing long-term storage and disposal of waste, as well as assessing potential environmental impacts.

Plutonium-239 is a significant isotope used in various applications, most notably in nuclear reactors and atomic bombs; thus, knowledge of its half-life is essential for safety protocols and risk assessment over the years. The longer half-life means that it remains radioactive for thousands of years, necessitating careful handling and monitoring to mitigate exposure risks to personnel and the public.
