“…An attempt was made to date glass by the fission track technique (Fleischer and Price, 1964). The U content was determined to be only 6 ppb, instead of the 75-300 ppb anticipated (Fisher, 1975). This low U content leads to an extremely low fossil track density (Table 2).…”

Number of Cores: 5 Total Length of Cored Section: 23.5 meters Total Core Recovered: 9.6 meters Principal Results: We drilled three holes at Site 353 near the north wall of the Vema Fracture Zone, but did not achieve the primary goal, penetration of basement. We abandoned Hole 353 at 384 meters, in Pleistocene turbidite sediments, because the Bowen drilling subassembly failed. In Holes 353A and 353B, we were unable to penetrate a basalt cobble layer, at least 13 meters thick, which underlies 168 meters of turbidite sediments; so we had to abandon these holes as well. Sediments collected indicate that the wall of the fracture zone has itself been a sediment source, in addition to the Amazon Cone area, which provided the bulk of the material.

“…The U content was determined by counting neutroninduced tracks on an interior surface, and has a large uncertainty (±50%) (Fisher, 1975). In view of the lack of positive results for the age determination, a more precise determination of the U content was not attempted.…”

“…The detection sensitivity (10 −12 gg −1 ) of uranium determination in natural water is much higher than those of other methods (Fisher, 1975). The large range of detection limits results, from the use of differentirradiation times and different neutron fluxes.…”

“…In general, it is difficult to analyse directly such small quantities of uranium in water by routine chemical means. However, the fission track registration technique is easier, less expensive and equally accurate compared to many other existing methods [1]. The determination of uranium content is of considerable interest to geologists, oceanographers, nuclear scientists and health physicists for various reasons, viz.…”

In the present investigation a nuclear track-etch technique using Solid State Nuclear Track Detectors was used to estimate the trace uranium concentration in water and soil samples collected from different sources and locations of the Amritsar and Bathinda cities of Punjab. The uranium concentration in the water samples collected from Amritsar was found to vary from 3.17 to 4.19 mg Á L À1 and in the Bathinda city it varied between 4.28 and 16.48 mg Á L À1 . A lake sample, collected from the NFL water works site in Bathinda city had a uranium content of only 1.21 mg Á L À1 which was several times lower than those samples collected from hand-pumps a n d t u b e -w e l l s f r o m t h i s a r e a . T h e uranium concentration in soil samples of Amritsar city was found to vary from 0.61 to 1.27 ppm. In addition, soil samples from other cities of the Punjab were analysed using the Gamma-spectroscopic technique to determine 226 Ra, 232 Th and 40 K concentrations in soil. The average values of the concentration of these elements was found to be 43.9, 55.9 and 101.7 Bq Á kg À1 respectively.
