Transfer coefficient defined as the ratio of radionuclide concentration in crops to that in soil is a key parameter to assess the concentration of the nuclide in crops in the fields. This coefficient fluctuates by several factors such as plant species, kinds of radionuclides, properties of soils and conditions of plant husbandary. In order to estimate the variations specifically by plant species and kinds of radionuclides, transfer rates of some radionuclides from culture solution to the edible parts were measured on crops such as rice plant, spinach, soybean, cucumber, eggplant and radish.<br>Results obtained are summarized below;<br>1) The orders of transfer rates are ⁶⁵Zn>⁵⁴Mn>¹³⁷Cs-⁶⁰Co>⁸⁵Sr>¹³¹I.<br>2) Differences of transfer rates are 2 to 3 orders of magunitude among crops and/or radionuclides.
