Highlights


7/2019

Automation System for radiochemical separation of radionuclides like thorium, uranium, plutonium, americium and strontium etc. in bioassay samples
\r\n



6/2019

An android based image analysis application has been developed to convert smartphone camera into a gamma radiation monitor. The developed application is ideal for use by first responders to detect suspected orphan sources/dirty bombs in the absence of specialized radiation detectors. Since the CMOS camera in a smartphone is sensitive to ionizing radiation, when the visible light is blocked from reaching the camera, the interaction of gamma rays with camera pixels produces bright spots in the image. These bright spots in the captured image are analyzed and correlated to the radiation exposure level.



6/2019

Backpack Gamma Spectrometry System (BGSS) has been developed to search, locate and identify orphan/lost radioactive sources in public domain without drawing the attention of the people. Radiation detection unit is packed in a backpack and the acquired gamma spectrum is communicated to a smart phone over Bluetooth. Android application in the smart phone analyses the spectrum for the presence of radioactive source and for the identification of the isotope. Smart phone gives the vibration alarm upon detecting a radioactive source.



5/2019

The Numerical Weather Prediction (NWP) models, such as The Air Pollution Model (TAPM) and Weather Research and Forecasting (WRF) model are extensively used for flow field simulation studies, including cyclone simulation (WRF). Typical flow field simulation using WRF model for Trombay site is shown in the Figures for two different atmospheric stability conditions, and for the simulation of cyclone NISARGA.



3/2017

These are deployed at all the exit points and around nuclear facilities to monitor any abnormal increase in the radiation level and to detect any attempt of unauthorized trafficking of the radioactive sources from the facility leading to increase in background radiation level



12/2016

In order to carryout Radiological Impact Assessment (RIA) of radionuclide leaching from Near Surface Disposal Facility (NSDF) or tailings pond at mining site, ground water modelling studies are carried out using in-house developed codes as well as state-of-the art numerical models. The results of one of the study carried out for tailings pond at Turamdih, Jharkhand



6/2016

Quad-rotor based Aerial Radiation Monitoring System (QARMS) has been developed for the quick assessment of radioactive contamination or search and locate orphan/lost radioactive source over a small inaccessible area. It can be quickly deployed and operated with minimum effort and no radiation exposure. QARMS consists of a flying unit and a ground control station. Flying unit consists of quad rotor, GM counter based radiation detection unit and ZigBee based communication device. The ground control station is a PC installed with mission planner software to control the movement of quad rotor and analysis the radiation data.



3/2014

Various systems and methodologies are developed for responding to any nuclear / radiological emergencies e.g. - aerial, land route monitoring methodology, any abnormal increase in radiation level at the site, meteorological parameters etc.

The Radiation Monitoring Watch (RMW) is a GM tube based, lightweight, compact, and ultra low power gamma radiation monitoring gadget in the form factor of a wrist watch. It indicates the prevailing dose rate, accumulated dose and current date & time. RMW is an ideal device for the first responders attending to an emergency or disaster to rule out the presence of a radiological event and can also assist the Emergency Response Personnel during the management of a radiological emergency. It is powered by a replaceable commercially available coin cell, capable enough for more than six months of continuous operation in background radiation. RMW alerts the user with an audible alarm when the dose rate exceeds the threshold.
