Gearing up to tackle possible chemical, biological, radiological and nuclear (CBRN) emergencies, premier research organisation DRDO is developing an array of ground-based and unmanned aerial systems to detect and map contamination zones in all geographical conditions.

The Defence Research and Development Organisation (DRDO) is developing such systems and equipments which will map a contaminated area with zero human exposure.

"We are developing ground-based and unmanned aerial systems which can be deployed deep in the affected zones to map and record level of contamination during CBRN emergencies," DRDO'S Chief Controller, Life Sciences, Dr W Selvamurthy said.

DRDO has a major ongoing program till 2014 to develop technologies to deal with CBRN emergencies.

"Under unmanned aerial system category, we are developing sensors which can be fitted on to Nishant and Rustom Unmanned Aerial Vehicles (UAVs) to monitor radiological activities.

Micro Aerial Vehicles (MAVs) are also being developed for effective deployment in more critical areas," he said.

DRDO has already conducted few demonstrations of its technology for the concerned Armed Forces and necessary modifications are being carried out as per the user's requirement.

The vehicle and building mounted systems, BMP and track-based vehicle have already been given to the services to detect all forms of CBRN emergencies, Dr Selvamurthy added.

Gwalior-based premier DRDO lab Defence Research and Development Establishment (DRDE) is the nodal body to carry out the project, while 12 other centres have also been roped in for development of other important systems.

"The total cost of the project is Rs 285 crore in which along with the technologies and contamination detection payloads we are also developing other equipments like sensors, clothing and safety measures for the soldiers who will operate in these areas," he said.
