The usefulness of sister chromatid exchange (SCE) induction as a measure of low-level radiation effect was examined in a benthic marine worm, Neanthes arenaceodentata. Larvae were exposed to /sup 60/Co radiation for 12 to 24 h at total doses ranging from 0.5 to 309 R and at dose rates from 0.04 to 13 R/h. Animals exposed at intermediate dose rates (0.5, 0.6, 1.25, 2.0, and 2.5 R/h) had SCE frequencies per chromosome about twice that of those receiving no radiation (controls), whereas those exposed at the higher dose rates (7.0 and 13 R/h) had SCE frequencies lower than the controls. Animals exposed at the lower dose rates (0.04 and 0.1 R/h) had lower SCE frequencies than those exposed at intermediate dose rates (and higher SCE frequencies than controls). The length of chromosome pair number one differed among metaphase spreads and was used as an index of chromosome condensation in a given metaphase. Because there is a possibility that chromosome morphology may affect the ability to resolve SCEs, morphology will be monitored in future studies. A preliminary experiment was performed to assess the effects of 2.2 and 11.5 R/h for 24 h on growth and development. Larvae observed at 6 and …

A proposal of using extrapolation algorithms as an analytical - numerical tool for the evaluation of the beam-beam effects in storage rings is formulated. These algorithms already known to experts of Applied Mathematics are described in some detail. Physical models for the beam-beam interaction effects on betatron motion and polarization of a test particle are discussed and put in such a form to allow the application of the extrapolation algorithms.

The potential environmental and socioeconomic impacts of the production of energy contained in hot dry rock (HDR) is surveyed here. In general, careful siting and timing and routine control measures should be adequate to prevent significant environmental harm; sites of particular ecological or visual and recreational value, however, may require more extensive (and more expensive) precautions such as using multiwell pads to reduce land disturbance and dry or wet and dry cooling towers to reduce or eliminate the consumptive use of water. The most important uncertainty among the environmental concerns is the seismic response of HDR formations to short-duration fluid injections at pressures above fracture thresholds; continued monitoring at HDR development sites is necessary. The direct socioeconomic impacts of HDR development should be relatively minor, owing to its capital-intensive nature. Of greater potential importance are the indirect jobs resulting from such development, which could cause significant demographic (and thus fiscal and social) impacts in sparsely populated regions. However, such indirect growth is not expected to begin until a large, stable HDR industry is established in a region, and thus its impacts are expected to be permanent rather than transient.

This system provides trigger signals at various times and clock signals at various frequencies for the CAMAC transient recorders of the plasma diagnostics system for the TMX-Upgrade. The timing system is designed so that all clocks are in fixed-phase relation to their corresponding triggers and to each other. Therefore, data recorded from the different diagnostics can be directly time compared. Trigger signals can be generated in 100-ns increments, with an uncertainty of 500 ps. The clock signals have a time uncertainty of less than 1 ns. The system is arranged so that these accuracies are maintained over the entire diagnostic room. The timing system is modular and uses mostly digital delay generators, signal fan outs, and frequency dividers. Because of the modular approach, the system can be arranged in several ways (producing many possible trigger times and sample rate clocks) and still maintain a system in which all clocks and triggers are in a fixed-phase relationship.

Results are presented for leach testing at 95/sup 0/C and 200/sup 0/C of SYNROC containing 9% and 20% simulated high level radioactive waste, synthetic hollandite and pervoskite samples, and natural zirconolite and pervoskite samples. Single phase synthetic minerals show much higher leach rates than natural mineral samples and polyphase SYNROC samples. Natural zirconolite samples with low radiation damage have leach rates at 200/sup 0/C based on U which are identical to those measured on SYNROC samples. Natural zirconolites with very large accumulated ..cap alpha.. dose and radiation damage have leach rates at 200/sup 0/C which are only 5 times higher than those of low dose samples.
