Early and continuing effects of combined alpha and beta irradiation of the lung:

Description: This report summarizes an inhalation exposure experiment that concerns early and continuing effects of combined alpha and beta irradiation of the lung of rats. Both morbidity at 18 months and mortality within 18 months after exposure were examined for rats exposed to the beta-emitter /sup 147/Pm, the alpha-emitter /sup 238/Pu, or both combined. The results were used to validate hazard-function models that were developed (1)for pulmonary functional morbidity at 18 months and (2) for lethality fr… more

Radioactivity Associated With Biota and Soils of the 216-A-24 Crib

Description: The 216-A-24 Crib was used from 1958 to 1966 to receive condensate (/sup 137/Cs, /sup 90/Sr) from the 241-A and 241-AX Tank Farms. In 1975, rabbitbrush plants (Chrysothamnus nauseosus) growing on the crib were found to contain radioactive materials. Highest levels of activity and densest stands of rabbitbrush plants were in the center of the second section of the crib where a Geiger--Mueller count rate meter showed surface exposure rates of certain plants to be as high as 125 times background. … more

Toxicity of tritium. [Chronic, low-dose exposure of mice and monkeys]

Description: Among radionuclides of importance in atomic energy, /sup 3/H has relatively low toxicity. The main health and environmental worry is the possibility that significant biological effects may follow from protracted exposure to low concentrations in water. To examine this possible hazard and measure toxicity at low tritium concentrations, chronic exposure studies were done on mice and monkeys. During vulnerable developmental periods animals were exposed to /sup 3/HOH, and mice were exposed also to … more

Research in radiobiology: Final report of work in progress in immunobiology of experimental host-tumor relationships

Description: Our work on the immunobiology of tumors induced in normal mice by non-ionizing radiation and chemical carcinogens has previously demonstrated a correlation between MHC molecule expression and the immunogenicity of tumors in a transplanted syngeneic host. Such that immunogenic or regressive tumors were found to demonstrate higher constitutive or inducible levels of MHC expression, while most virulent, aggressive tumors exhibited a low level of MHC Class I expression. We attributed much of the co… more

Dosimetry, instrumentation and exposure chambers for dc magnetic field studies

Description: The principal objective of this report is to describe in detail an exposure chamber that was developed at the Lawrence Berkeley Laboratory for automated, noninvasive studies of rodent physiology during exposure to high DC magnetic fields. A second objective is to discuss some of the unique instrumentation problems that must be overcome in order to record bioelectric signals from laboratory animals in the presence of a magnetic field. Finally, a description will be given of the various dosimetry… more

Nuclear medicine program progress report for quarter ending December 31, 1992

Description: We describe the synthesis of the cis- and trans-iodovinyl isomers of the new ORNL cholinergic-muscarinicreceptorligand, 1 -azabicyclo[2.2-2]oct-3-yl[alpha]-hydroxy-[alpha]-(1-iodo-l-propen-3-yl)-[alpha]-phenylacetate ( IQNP''). This agent is prepared in high radiochemical yield, and the racemic mixture shows high specificity and selectivity for the cerebral and myocardial receptors. Since two chiral centers are present in this molecule, it is important to evaluate the importance of the absolute… more

Analytical approaches to and interpretations of data on time, rate, and cause of death of mice exposed to external gamma irradiation

Description: Young adult male and female mice of inbred strains, A, BALB/c, C57BL/6, and C57L, and B6CF/sub 1/ and F/sub 2/ hybrids were exposed to daily duration-of-life external /sup 60/Co ..gamma.. irradiation. Age at death was recorded, and most decedents were necropsied to ascertain occurrence of major types of tumors. Age- and cause-specific mortality or incidence rates were derived, and their regressions on age were fitted with polynomial equations by least-squares procedures. Age-specific and age-ad… more

Cataract production in mice by heavy charged particles

Description: The cataractogenic effects of heavy charged particles have been evaluated in mice in relation to dose and ionization density (LET/sub infinity/). The study was undertaken due to the high potential for eye exposures to HZE particles among SPS personnel working in outer space. This has made it imperative that the relative biological effectiveness (RBE) in relation to LET/sub infinity/ for various particles be defined so that appropriate quality factors (Q) could be assigned for estimation of risk… more

Radiation Carcinogenesis. Progress Report III, 15 March 1975--15 March 1976.

Description: The attention of forensic pathologists has been drawn to the criteria essential for the recognition of radiation death or injury in the hope that such cases will be better recognized and that some false claims of radiation damage might be prevented at the local level. The results of experiments on parabiont rats, one of which had been irradiated with 1000 R of 250 kVp x-ray, the other shielded, are reviewed. With controls and related special studies the total is over 3000 pairs equally divided … more

Radiation Carcinogenesis. Comprehensive Final Report, 16 May 1979-31 December 1980

Description: This abstract covers three main areas of investigation: mesothelioma induction by asbestos, radiation tumorigenesis and transplantable tumors. Canadian and Rhodesian asbestos fibers have been administered under anesthesia to rats by intratracheal, intrapleural and intraperitoneal injection. Additional groups were given 3-methylcholanthrene or x-radiation along with asbestos. A large series of mice also treated as above have displayed mesotheliomas. In addition, glass fiber injections and feedin… more

Hantavirus testing in rodents of north-central New Mexico 1993-1995

Description: In 1993, an outbreak of a new strain of hantavirus in the southwestern US indicated that deer mice (Peromyscus maniculatus) was the primary carrier of the virus. In 1993, 1994, and 1995 the Ecological Studies Team (EST) at Los Alamos National Laboratory surveyed small mammal populations using live capture-recapture methods in Los Alamos County, New Mexico, to determine seroprevalence of hantavirus in this region. EST used trapping grids in 1993 and 1994 and used trapping webs in 1995. Grids wer… more
