Absorbing fission products from soil is one source of crop contamination from radioactivities. The activity of fission products in soil changes with types of soil. This experiment studied the effect of agrochemical properties of soil on absorption of
90
Sr by spring wheat using six types of soil. The result showed that amount of exchangable calcium and pH value are significantly negative correlated with amount of
90
Sr uptaken by wheat plant. The differences between six types of soil are 1—6 times in amount of
90
Sr absorbed and concentration coefficient in wheat plant. The concentration coefficient in wheat seed varied in the range of 0.08 to 0.59.
