A new noninvasive method with a very low local radiation exposure (less than 2 mSv) is based on the principle of recording and assessment with an externally located gage of characteristic radiation of stable iodine of the thyroid with the energy of 28 KeV, excited by externally located sources of irradiation. The method was given the name of radiofluorescent assay (RFA) or x-fluorescent scanning of the thyroid. A series of units and methods of investigation were developed for RFA. The reproducibility, accuracy and radiation exposure of the above diagnostic method were assessed. A study was made of RPA values in healthy subjects (stable iodine concentration in the thyroid 500(+)-40 micrograms/g; stable iodine amount in the organ -10.3(+)-1.0 mg; Fe mass -20.2(+)-1.4 g) and their correlation with age, height, body mass and surface, 131I absorption, the blood concentration of TSH, T3, T4.
一种新的非侵入性方法，其局部辐射暴露量极低（小于2毫希沃特），该方法基于以下原理：通过外部辐射源激发，利用位于体外的测量仪记录和评估甲状腺中能量为28千电子伏的稳定碘的特征辐射。该方法被命名为放射荧光测定法（RFA）或甲状腺X射线荧光扫描法。针对RFA开发了一系列装置和研究方法。评估了上述诊断方法的可重复性、准确性和辐射暴露情况。对健康受试者的RPA值（甲状腺中稳定碘浓度为500（±）-40微克/克；器官中稳定碘含量为-10.3（±）-1.0毫克；铁质量为-20.2（±）-1.4克）及其与年龄、身高、体重和体表面积、131I吸收率、促甲状腺激素（TSH）、三碘甲状腺原氨酸（T3）、甲状腺素（T4）血浓度的相关性进行了研究。
