<I>A simple apparatus was made for the X-ray fluorescent anlaysis of iodine concentration of the thyroid. The apparatus consists of</I> <SUP>241</SUP>Am <I>γ-ray source of 300mCi and pure</I> Ge<I> detector of 50mm<SUP>2</SUP>×5mm. Diverging collimator was designed to achieve a full view of the thyroid. The detectable concentration was 0.2mg iodine/g tissue assuming the coefficient of variance of 30% and the counting time of 5 minutes. Measurement was performed for autopsied 10 thyroids and the results were in good correlation with those by neutron activation analysis (r=0.93) . Iodine concentration ranged 0.3-1.2mg/g (mean 0.6mg/g) and compared well with the data in literatures. This technique is useful for the in vivo measurement of thyroidal iodine content in patients</I>.
