Just an update to what I believe was the FDA links in post #2  https://www.fda.gov/...ing/default.htm

Focus should be done on really radiological isotopes which may be present in water or soil (either from a naturally occurring source or resulting from a man-made disaster )  e.g. Technetium-99 for medical investigation , Iodine -131 for medical treatment or Cesium -137 + strontium-90 + Iodine -129 in the area of Nuclear Power Plant / damage to a nuclear facility from a natural disaster.  Such group of isotopes are really classified as radiological hazards.

 

In addition, you should be aware of the condition of the water used for production and manufacture in your facilities. Radiological hazards can become incorporated into food through the use of water that contains the radionuclides during food production or manufacture. There are areas in many country where high concentrations of some radionuclides, such as radium-226, radium-228, and uranium, can be detected in well water.

 

Element composition in food are C , H , O , N, Ca, K, Mg, P, S, Fe, Mn , Zn etc .  Exposure of food to ionizing radiation in the form of x-rays, gamma rays or electron beams , Radicidation or Radappertization can not cause the radioactive isotopes in Food. Irradiated food are safe food in many country. Just label to declare the irradiated food status in compliance with labelling regulatory requirement in destination country is OK. Be aware that fraudulent labelling practice is one kind of food fraud issue.

Anyway, if you are also aware of any potential hazards from irradiated material (for example, it is not permitted in the intended country of sale) then this should also be considered as a hazard.
