In this paper sustained effect of micronucleus formation in bone marrow cells induced by absorption dose of 134 Cs in skeleton was studied. The results indicated that a fitted equation to describe the retention of 134 Cs in bone marrow cells is obtained as follows: R(t)=0.0029e -0.121t . Where the T 1/2 in skeleton is 5.73d. Experimental results showed that obvious increase of micronucleus formation could be induced by 134 Cs with a threshold dose as 0.93kBq/g. The relations between injected dose(X
kBq/g) and micronucleus formation rates(Y
%) can be expressed by an power function Y=0.246X 0.307 . In accordance with the peculiarity of internal exposure with 134 Cs
sustained effect of micronucleus formation in bone marrow cells may continued to 47 days.
