[en] A short summary of the programmes of 'ADMIT' (FAO/IAEA) and the developments in analytical detection methods for radiation processed foods has been given. It is suggested that for promoting the commercialization of radiation processed foods and controlling its quality, one must pay more attention to the study of analytical detection methods of irradiated food

[en] First, the countries which approve irradiated foods as those for human and the kind of approved foods were mentioned. Description was also made of the estimation of wholesomeness of irradiated foods, which was decided in 1969 by the expert committee composed of FAO, IAEA, and WHO. A long-term experiment on the toxicity including carcinogenesis of irradiated potatoes, which was carried out by the author, was stated. Experiments on wholesomeness of irradiated foods which were made in various countries were introduced, and their methods were considered. Lastly, the author's opinions were stated as follows: (a) it is possible to feed experimental animals with foods which contain irradiated or non-irradiated foods, and (b) in order to investigate genetic wholesomeness of irradiated foods, in vivo examination using mammals must be done mainly, because it offers informations useful to know the effects of irradiated foods on human body.

Nevertheless, research workers in many countries are actively attempting to use such techniques to improve the basic plant stock the farmer uses - and have already achieved some notable successes.
