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(More)
