X-rays are dangerous mutagens.

Explanation:

X rays are the potential mutagens which means that they can cause random changes in the DNA of organisms. X rays are ionizing radiations and produce the free hydroxyl radicals which in turn target the phosphodiester bond of DNA and leads to mutations.  

Ayden was told to wear the protective vest since a small exposure to X rays can serve as a cause of mutations. Wearing the protective gears would have prevented direct exposure of his body surface to the X rays. It would reduce the chances of any potential harmful mutations in Ayden.
