  5. Work Experience
  6.  

     

    1969-2001 Bhabha Atomic Reseach Centre, Environmental Assessment Division, Mumbai.

    Work involved:

    Development of radiation protection instrumentation and nucleonic gauges for in situ measurements of soil density, moisture, thickness of articles using various radioisotopes.

    Nuclear and related Techniques in Environmental pollution Monitoring:

    Analysis of Environmental samples (air particulates on filters, soil, coal, coal ash from thermal power plants, vegetation and water) for toxic elements using Energy Dispersive X-Ray Fluorescence (EDXRF) and Neutron Activation Analysis (NAA) Techniques.

    Techniques of collection, preparation and processing of environmental samples. Development of air particulate samplers- low and high volume TSP and PM-10 samplers.

    Data generated from the measurements were also analyzed statistically using computer programmes like Factor Analysis to predict sources of pollutants in the environment at the sampling sites. Preparation of environmental assessment reports.

    Besides, I have acquired the expertise in the repairs and installation of the Si(Li) and HPGe detector based x ray and gamma ray spectrometric systems used for the above measurements. I was instrumental in the development of a laboratory for troubleshooting and repair of HPGe and Si(Li) detector capsule comprising cooled FET, feed back circuits including pre-amplifiers.
