Abstract

Heterogeneity of uranium in water from south peninsular India

Highlights

  • The largest proportion of human exposure to radiation comes from natural sources – from external sources of radiation, including cosmic and terrestrial radiation, and from inhalation or ingestion of radioactive materials

  • Results of the analyses of water samples collected from different sources in the south coast of India show that uranium concentrations vary from 0.82 μg/l to 7.32 μg/l equivalents to the specific activity of 10.33Bq/m3 and 92.23Bq/m3, respectively

  • The arithmetic mean (AM), geometric mean (GM) and geometric standard deviation (GSD) of the measured values for the two zones are presented in the Table 1

Summary

INTRODUCTION

The largest proportion of human exposure to radiation comes from natural sources – from external sources of radiation, including cosmic and terrestrial radiation, and from inhalation or ingestion of radioactive materials. Effective technique known as ‘dry method’ has been used for the analyses doses resulting from the intake of natural radio nuclides can be (Jojo et al, 1994).Dielectric fission track detectors (Makrofol – determined directly from measuring its concentrations in the KG) cut in the form of circular discs of 1.3 cm diameter were body or estimated from concentrations in intake materials such properly washed and rinsed with the double distilled water.
