Can you touch cadmium?
As a plated surface on a component, cadmium does not represent a risk to health – cadmium is not easily absorbed through the skin, so handling cadmium plated items poses no risk to the user. The main risk to health is cadmium dust or vapor, which can be generated by, for example machining cadmium, or welding it.
