for a low-level liquid scintillation counter and used to measure samples collected at several atolls in the Marshall Islands. The /sup 241/Pu/sup 239,240/Pu ratio is generally approximately 20 when decay-corrected back to 1956. measured, However, ratios of from 10 to 26 were indicating that the /sup 241/Pu/sup 239,240/Pu ratios may be used to detect particular sources of plutonium isotopes, i.e.y different nuclear detonations or from nuclear waste disposal.’ from Measurements of plutonium and /sup 210/Pb have been made of a nuclear waste disposal site 4000 m deep located off the coast of New York, USA. Because of the low-level activity of the plutonium present, medsurement times often exceeded 10,000 min. The long-term reliability of the system is proved by these measurements and by the results of the interlaboratory calibration.; Major Descriptors: *ENVIRONMENTAL MATERIALS -- ALPHA DETECTION; *ENVIRONMENTAL MATERIALS -- GAMMA DETECTION; *LOW LEVEL COUNTERS -MICROPROCESSORS Descriptors: AGE ESTIMATION; ALPHA SPECTRA; ANALOG-TO-DIGITAL CONVERTERS; BACKGROUND RADIATION; DATA ACQUISITION; DATA PROCESSING; GAMMA SPECTRA; LI-DRIFTED GE DETECTORS; LIQUID SCINTILLATION DETECTORS; LOW LEVEL COUNTING; NAI DETECTORS; PLUTONIUM 239; PLUTONIUM 240; PLUTONIUM 241; SAMPLE PREPARATION; SEAWATER; SI SEMICONDUCTOR DETECTORS; SURFACE BARRIER DETECTORS Broader Terms: ACTINIDE ISOTOPES; ACTINIDE NUCLEI; ALPHA DECAY RADIOISOTOPES; BETA DECAY RADIOISOTOPES; BETA-MINUS DECAY RADIOISOTOPES ; CHARGED PARTICLE DETECTION; COMPUTERS; COUNTING TECHNIQUES; DETECTION ; ELECTRONIC CIRCUITS; ELECTRONIC EQUIPMENT; EQUIPMENT; EVEN-EVEN NUCLEI; EVEN-ODD NUCLEI; GE SEMICONDUCTOR DETECTORS; HEAVY NUCLEI; HYDROGEN COMPOUNDS; ISOTOPES; LI-DRIFTED DETECTORS; MATERIALS; MEASURING INSTRUMENTS; MICROELECTRONIC CIRCUITS; NUCLEI; OXYGEN COMPOUNDS; PLUTONIUM ISOTOPES; PROCESSING; RADIATION DETECTION; RADIATION DETECTORS; RADIATIONS; RADIOISOTOPES; SCINTILLATION COUNTERS; SEMICONDUCTOR DETECTORS; SOLID SCINTILLATION DETECTORS; SPECTRA; WATER; YEARS LIVING RADIOISOTOPES Subject Categories: 440101* -- Radiation Instrumentation -- General Detectors or Monitors & Radiometric Instruments 520301 -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Water ~-- (1987) 400103 -- Radiometric & Radiochemical Procedures -- (-1987) INIS Subject Categories: E41* -- Particle & Radiation Detection & Measuring Instruments & Methods 10/5/735 (Item 435 from file: 00885705 EDB-82-060547 Title: Radiating paradise Author(s): Heuseler, Subfile: DE 103) H.

Country of Origin: Germany, Federal Republic of Abstract: Decades after the a-bomb experiments in the desert of Nevada, cases of illness occur more frequently: many former soldiers who had to observe the tests as spectators suffer from leukemia, skin and thyroid ulcers. Even worse are the late results of the nuclear weapon tests in the Pacific: on Bikini and Eniwetok, once paradise-like atolls, the death from radiation is waiting, an attempt to recultivate the bombed > Bikini Atoll failed.; Major Descriptors: *HUMAN POPULATIONS -- DELAYED RADIATION EFFECTS; *MILITARY PERSONNEL -- DELAYED RADIATION EFFECTS; ~- RADIATION HAZARDS *NUCLEAR EXPLOSIONS ™ o nm = Descriptors: BIKINI; MAN; NEVADA TEST SITE; NUCLEAR WEAPONS = Broader Terms: ANIMALS; BIOLOGICAL EFFECTS; BIOLOGICAL RADIATION EFFECTS; EXPLOSIONS; HAZARDS; HEALTH HAZARDS; ISLANDS; MAMMALS; MARSHALL ISLANDS ; MICRONESIA; OCEANIA; PERSONNEL; POPULATIONS; PRIMATES; RADIATION
