AbstractAbstract
[en] Using dimethylsulfoxide (DMSO) as a labelling aid, insulin 126I of radioimmunoassay use has been effectively prepared. A small amount of DMSO was added to usual labelling mixture and the reaction time was controlled. The labelled insulin obtained in such a way showed improved bindabilities to the antibody and thus expressed larger dose-gradients in the plots of standard dose-response curves even though the labelling rate was decreased to some extent. However, by extending the reaction time to about 1 min, average labelling yield of 30% could be obtained. The average increase of bindability (B/F) in definite antiserum dilution was 2.5 comparing with 1.5 obtained in the absence of DMSO. Thus, the net bindability increase was 70% of those obtained in the absence of DMSO. By means of NMR spectrometry, it has been confirmed that the DMSO in the labelling mixture is converted to dimethylsulfone by chloramine-T. The results, generally agreed with the Stagg's postulation, were discussed in view of a competitive oxidation of DMSO with disulfide linkages of the insulin molecule by the chloramine-T. (author)

AbstractAbstract
[en] We describe a simple method for determining the neutron-absorption cross sections of radioactive nuclides and its application to 22Na and 126I. These nuclides are produced by fast-neutron reactions in cadmium-wrapped and unshielded samples simultaneously irradiated with cobalt flux wires. Values for the thermal cross section, sigma0, the resonance integral, Σ', and s0 are calculated from the data using the Westcott convention. The results are as follows: for 22Na, sigma0 = (5.11 +- 0.31) x 104 b, s0 = 2.3 +- 0.1, and Σ' = (1.0 +- 0.1) x 105 b; for 126I, sigma0 = (9.0 +- 5.0) x 103 b. 1 figure, 4 tables

AbstractAbstract
[en] The atomic nuclei are a mesoscopic system and have complex structures and dynamics. The investigation of such system gives a vibrant information of underlying symmetries that existed in it. Rotational motion of the nuclei introduces many new symmetries and collective degree of freedom. Consequently, many new phenomena have been observed, e.g. backbending, signature splitting, signature inversion, chirality, etc. With the help of symmetries arguments, many of them can be explained nicely, for example energy degenerate bands of same parity due to chiral symmetry breaking. In mass region A ≈ 130, a large number of doubly odd nuclei exhibit the possible chiral bands as well as signature partners bands. The objective of the present work is to investigate these symmetry-based bands in doubly odd nuclei in mass region A ≈ 130 (specially chiral bands). Additionally, the cause of signature inversion was also addressed. Two nuclei were extensively studied, one is 126I, and another is 130La using the framework of lifetime measurements

AbstractAbstract
[en] In medical applications of radionuclides, almost exclusively low-activity and short-lived wastes are produced. This requires little expensive waste management if there is an appropriate organization and training of the personnel. In scintigraphic examinations the prevailing part is carried away from the department for nuclear medicine by the patient as incorporated activity (on average more than 90%). In the case of the frequently used Tc-99m, the radioactive material remaining there, e.g. injection syringes or similar objects, may decay in situ in suitable containers. For other diagnostic radionuclides, whose activities and volumes are samller, there should be a place of decay within the range of the department. Difficulties arise in the mangement of the large amounts of low-activity waste produced in in vitro diagnostics, at present mostly iodine-125. In smaller laboratories, the liquid waste is disposed of by means of controlled dilution, whereas for many samples collection even of the low-activity liquids may become necessary. The very voluminous, but very low-activity waste may, according to the space available, be stored for decay or handed over to a conditioning agenca for ultimate storage. The management of H-3 and C-14 compounds does not result in a real problem of radiation protection; but the solvent used for counting must not be admixed to the inactive waste water. For radioiodine therapy, a carefully designed decay facility seems to offer the best opportunity for waste disposal. (orig.)

Bei der Anwendung von Radionukliden in der Medizin fallen fast ausschliesslich schwachaktive oder kurzlebige Abfaelle an. Das ermoeglicht bei entsprechender Organisation und Schulung des Personals eine wenig kostenaufwendige Entsorgung. Bei szintigraphischen Untersuchungen wird der ueberwiegende Anteil als inkorporierte Aktivitaet vom Patienten aus der nukleramedizinischen Abteilung mitgenommen (durchschnittlich mehr als 90%). Das dort verbleibende radioaktive Material, wie Injektionsspritzen u.ae., kann im Falle des am haeufigsten verwendeten Tc-99m in geeigneten Behaeltern an Ort und Stelle abklingen. Fuer andere diagnostisch verwendete Radionuklide, deren Aktivitaet und Volumen kleiner ist, sollte eine Moeglichkeit fuer das Abklingen im Bereich der Abteilung vorgesehen werden. Schwierigkeiten bereitet die Entosrgung der grossen Mengen an schwach-aktivem Abfall, der bei der in vitro Diagnostik entsteht, zur Zeit vorwiegend Jod-125. Der fluessige Abfall wird in kleineren Laboratorien durch kontrollierte Verduennung beseitigt, waehrend bei vielen Proben eine Sammlung auch der schwachaktiven Fluessigkeiten notwendig werden kann. Der sehr voluminoese, aber sehr schwachaktive Abfall kann je nach vorhandenem Raum zum Abklingen gelagert oder einem Konditionierer zum Endlagern uebergeben werden. Die Entsorgung von H-3- und C-14-Verbindungen bildet kein eigentliches Strahlenschutzproblem, doch darf das zur Zaehlung verwendete Loesungsmittel nicht dem inaktiven Abwasser beigemengt werden. Fuer die Radiojodtherapie scheint eine sorgfaeltig geplante Abklinganlage die beste Moeglichkeit der Entsorgung zu bieten. (orig.)Original Title

AbstractAbstract
[en] The yrast band in "1"2"6I was found to have signature splitting and signature inversion in our earlier work. We explained the cause of signature inversion to be the change in the axis of rotation from the shortest axis to intermediate axis of the triaxial nucleus. We utilized the theoretical frame work of particle rotor model and cranking model. The triaxial shape parameters were determined from these calculations. We are now trying to determine the shape parameters from the experimental values of the quadrupole moment derived from the analysis of lifetimes using the Doppler Shift Attenuation Method (DSAM). Furthermore, we are trying to understand the phenomenon of back bending which occurred at the angular momentum just above the signature inversion. Our investigation will throw some light if the occurrence of back bending at a certain rotational frequency was influenced by the change in the axis of rotation at the signature inversion

AbstractAbstract
[en] There has been growing interest to understand the role of triaxial nuclear shapes in many interesting phenomena like chirality, signature inversion. In our recent study of 126I, we have theoretically established the cause of signature inversion to be the change in the axis of rotation from the shortest to intermediate axis of the triaxial nucleus. In the present work, we are trying to establish the same result experimentally. An attempt has been made to find the lifetimes of the high spin states of 126I by the Doppler shift attenuation method (DSAM)
