Measurements were made of the cesium-137 content in human muscle, total diet, and cereals collected in Japan during the period from February 1960 to May 1962. The simple methods of evaluation of mean levels in the human body proposed are based on distribution studies on the common cesium irrespective of potassium concentration or the cesium unit. The total body burden was estimated as 3.2 -- 4.0 m μC for the period from August 1960 to January 1962 and it rose up to 7.6m μC in March 1962 in correspondence with the increased fallout deposition rate in Autumn 1961. The daily intake of cesium-137 by Japanese people was 29 μμ C, on average, for the period from August 1960 to August 1961 and increased to 50 μ μC in February 1962. The contribution of cesium 137 by cereals to the total intake was estimated as approximately 40% for the period from November 1960 to November 1961 and it decreased to 32% in February 1962. The relative decrease was attributed to the increase in the daily intake, probably other than cereal, through leafy vegetables.
