The standards reduce the annual upper dose limit for radioactive cesium to 1 mSv. The upper dose limits are calculated using age divisions: newborn babies, 1–6 years, 7–12 years, 13–18 years, and 19 years and above. The strictest values are applied. As food intake varies between gender in the 13–18 years and 19 years and above categories, the standards also contain gender specific values.The provisional regulation value for regular food products will be set at 1/5 and drinking water at 1/20. Given that children are susceptible to radiation effects, newly added values for baby foods and milk will also be set at 1/2, the value for regular food products. In addition, the new standards do not cover radioactive iodine and uranium, as these could not be detected in food products.
