Low dose exposure in the environment is an important area of research
nowadays.This book is based on our investigation on assessment of
alpha-activity for fishes and vegetables along with annual dose
committed using samples from 4 important sites in this regard. A
comprehensive background for this work is presented before the data. The
book is organized as follow: Chapter 1 presents a brief introduction
about ionizing radiation as pollutants .objectives of our work related
with fish and vegetables are described in Chapter 2. In Chapter 3
discussion has been taken up on radioactive particles. Discussion with
dose and units of radioactivity has been made in Chapter 4. Chapter 5
contains discussion on radio-toxicity and annual limits of intake. Topic
of discussion of Chapter 6 is the effects of ionization radiation on
cells and tissues. The Chapter 7 deals with a brief overview of
detectors for analysis of environmental radio-nuclides. In Chapter 8
details of measurement has been incorporated. In Chapter 9, the subject
matter of discussion is alpha radioactivity and dose assessment at
different sites. The book ends with a conclusion .
