Highlights


6/2019

Automated air moisture collector is designed and developed for collection of air moisture for analysis of tritium in environment around PHWR type power plants. This indigenously developed system collects moisture at low humidity levels and can also be used for collection of long-time cumulative sample in comparison to the present method of random sample collection. The system is at testing stage and it is planned to deploy at Nuclear Power Plant sites.



6/2019

Varying amounts of chemicals of anthropogenic origin are found to have carcinogenic or mutagenic properties. Exposure can occur when these agents are present in food, air or water. Monitoring of these carcinogens involves sampling and analyte specific method development of trace level analysis.



5/2018

RADCOM (Radiation Dose Computation Model) is a computer program written in Visual Basic programming language.
\r\nIt Predicts environmental transfer of radionuclides and dose assessment following releases to atmospheric and aquatic system from nuclear installation/facilities.



1/2018

Environmental Gamma Spectrometry System (EGSS) is a standalone, solar powered, and battery-operated unit that can be installed in open field. It has a 2” diameter by 2” height NaI (Tl) scintillator-based gamma spectrometer, together with GM tube based gross gamma detectors.
\r\nThe multichannel analyser used in the spectrometer is developed in-house and eliminates the requirement of a PC for data logging.



12/2015

Use of remotely sensed data (Landsat, LISS-III) and GIS for estimation of population and its distribution, up to village level, around nuclear power plants.



6/2010

Environmental Surveillance is an integral part of the operation of the nuclear facilities to demonstrate compliance to the prescribed regulatory norms and to prove that there is no discernible radiological impact to the surrounding environment and to the public. Environmental surveillance includes collection and analysis of various environmental matrices around Nuclear Power Plants upto 30 km radial distance and estimation of dose to Members of public. The results of the annual environmental surveillance programme clearly indicated that the dose to the member of public at fence post is only a small fraction of regulatory limit of 1000 µSv/y and negligible compared to the dose received by the public from natural sources (~ 2400 µSv/y).



1/2010

Under this programme environmental gamma radiation monitoring, using thermo-luminescent dosimeters (TLDs) around all the nuclear installations in India is being carried out by EMAD. Over large areas the TLD-recorded radiation profiles can reflect the environmental gamma
\r\nradioactivity distribution pattern and even seasonal variations in the radiation levels above ground may be delineated.



4/2002

IERMON has an operational network of 500 or more unattended monitoring stations. As on July 31, 2019, IERMON is operational with 505 stand-alone solar powered GSM communication based Environmental Radiation Monitors.



5/1969

Evaluation of impact and assessment of build-up of radionuclides in the environment due to operation of various facilities of BARC. Environmental matrices: Fresh water, soil, vegetation, marine matrices like Sea water, sediment, biota, air particulate and air moisture collected and analysed for radionuclide content.



5/1969

Environmental Surveillance covering an area in the radial zones from 1.6-30 km distance with respect to BARC, Trombay. Radioactivity of anthropogenic origin estimated in local food consumed, mostly fish and salt and dose imparted to the public, over and above the natural background estimated. There are 21 regular monitoring locations. The environmental surveillance carried out from 2007-2017 indicates that radioactivity in different environmental matrices have remained almost at the same levels.

Scanning Electron Microscopy (SEM) allows for visual observation of an area of interest in a completely different way from that of the naked eye or even normal optical microscopy. SEM images show simple contrasts between organic-based and metallic-based materials and thus instantly provide a great deal of information about the area being inspected. At the same time, Energy Dispersive X-Ray Spectroscopy (EDS), sometimes referred to as EDAX or EDX, can be used to obtain semi-quantitative elemental results about very specific locations within the area of interest. EDS technique can detect elements from carbon (C) to uranium (U) in quantities as low as 0.1 wt%.

X-ray fluorescence spectrometry (XRF) is a well-established analytical technique for qualitative and quantitative elemental analysis (sometimes from Be to U) of a wide variety of samples. In particular, the truly multi-element character, acceptable speed and economy, ease of automation and the possibility to directly analyse solid samples are the most important features among the many that have made it a very mature analytical tool for routine quality controls in many industries, as well as for analytical support for the research laboratory.

A geographic information system (GIS) is a framework for gathering, managing, and analysing data. Rooted in the science of geography, GIS integrates many types of data. It analyses spatial location and organizes layers of information into visualizations using maps and 3D scenes. With this unique capability, GIS reveals deeper insights into data, such as patterns, relationships, and situations—helping users make smarter decisions.



Technologies Developed

(10-06-2019) Development of National Nuclear Forensic Reference Database for front end fuel cycle materials


For nuclear forensic investigation availability of the reference forensic database is of utmost importance for tracing the origin of the confiscated material. Development of this database in front end fuel materials, has been initiated. Mine and mill samples from Indian operating plants are being collected and analysis of various forensic signatures is being carried out for generation of database. This database will serve as an input for developing National Nuclear Forensic Library.
