Transmission scanning II

Description: From nuclear science symposium; San Francisco, California, USA (14 Nov 1973). Work has been continued on the development of techniques for imaging spatial elemental distributions by means of differential absorption about the K- absorption edge of the particular element Z. A method to correct for spurious effects due to differential absorption in overlying absorber is described. Initial clinical studies of thyroid iodine images on patierts are presented. Application of absorption edge transmissi… more

Natural iodine and iodine-129 in mammalian thyroids and environmental samples taken from locations in the United States

Description: From symposium on enviromnental surveillance around nuclear installation; Warsaw, Poland (5 Nov 1973). Bovine and other mammalian thyroids, air, precipitation, water, grass, and milk samples from selected locations were analyzed for their natural iodine and iodine-129 content. Particle filters and activated charcoal beds were used to collect the particulate and gaseous iodine fractions from the air. Anion exchange was used for the separation of iodine from liquid samples. Cumbustion methods wer… more

Comparative evaluation of $sup 123$I and /sup 99m/Tc for thyroid studies

Description: A comparative study of the metabolism of /sup 129/I and /sup 99m/Tc in the thyroid was made. Thirty-minute uptake curves were determined for 26 patients and comparison images were obtained at 30 minutes With /sup 99m/Tc and at 30 minutes and 24 hours with /sup 123/I. Both radionuclides can be used to advantage in assessing thyroid function and anatomy. The reasonable cost of /sup 123/I adds to its clinical value. (HLW)

Radioecology of iodine-129: an interim report

Description: Radioactive isotopes of iodine are Produced during nuclear fission in reactors and in weapons tests and to a limited extent in nature. Because of its extremely long half-life (1.6 x 10/sup 7/ yr) 1291 has the potential for accumulation in the environment from longterm, chronic releases from nuclear facilities. Possible problems associated with such an accumulation, including transfer of the /sup 129/I through the biosphere and resultant radiation doses to man and other organisms are discussed. … more
