Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

In the ion cyclotron range of frequency (ICRF) heating experiments on GAMMA 10, wave-wave and wave-particle interactions are investigated. Low-frequency fluctuations of around 100 kHz with beat frequencies among the AIC modes have been observed. These low-frequency modes are also detected in the signal of electrostatic probes in the central cell and in the signal of end-loss high-energy ion detector. Axial transport (velocity space diffusion) of high-energy ions due to beat waves among the AIC modes is clearly indicated. On the other hand, radial transport of high-energy ions due to the drift-type fluctuations has been observed in the central cell. The excitation of low-frequency magnetic fluctuations of which frequencies, fLF, are less than 1 MHz and satisfy the relation of fLF = fICRF - fAIC, where fICRF is the frequency of the heating ICRF wave and fAIC the frequency of the AIC modes. The parametric decay of the heating ICRF waves to the AIC modes and low-frequency waves will be a possible mechanism.
