Lecture Notes: Radioactivity in Bananas and Other Topics
Radioactivity in Bananas
-
Source of Radioactivity:
- Bananas contain radioactivity due to the presence of Potassium-40 (K-40).
- K-40 is a natural isotope of potassium.
-
Decay Process:
- K-40 has a half-life of approximately 1.25 billion years.
- It decays into calcium-40 and argon-40.
-
Health Implications:
- The radioactivity in bananas is considered a natural occurrence.
- It poses no health risk to humans due to low levels of radioactivity.
- According to the Canadian Coalition for Nuclear Responsibility, humans are already radioactive due to the natural potassium in their bodies.
