Thyroid Measurement Method for Monitoring Laboratory Workers Exposed to (125)I.

摘要

We describe here the standardization of a technique for the estimation of /sup 125/I in the thyroid gland of laboratory workers involved with /sup 125/I labelling techniques. It is based on a comparison with a standard curve obtained by placing in a thyroid neck phantom various calibrated standard sources of /sup 125/I. Its sensitivity was calculated around 0,8 - 1,7 nCi. The precision of our measurements was avaliated in a range of 1.35 - 310.5 nCi and the coefficient of variation obtained varied from 2,2% to 26,3%. The accuracy of our ''in vivo'' measurements was checked by analyzing the influence of the shape and the size of the thyroid in the neck phantom. (Atomindex citation 20:018643)
