Vitamin B12 (cobalamin) is particularly sensitive to radiation.
Radiation can break down the chemical bonds in vitamin B12, rendering it inactive. This process, known as radiolysis, occurs when high-energy radiation interacts with molecules, leading to their decomposition.
While all vitamins can be affected by radiation to some extent, vitamin B12 is especially susceptible due to its complex structure.
Exposure to radiation can occur from various sources, including:
* **Medical procedures:** X-rays, radiation therapy, and nuclear medicine scans.
* **Environmental sources:** Nuclear accidents, radioactive waste, and natural background radiation.
* **Food irradiation:** Used to extend shelf life and reduce foodborne pathogens.Note: The amount of radiation required to significantly degrade vitamin B12 in food is generally higher than what is typically encountered in everyday life. However, in situations involving high-dose radiation exposure, such as radiation therapy or nuclear accidents, vitamin B12 levels can be significantly depleted.
