Now these days, terrorist attack is become more prominent worry compare to others reasons. Terrorist can easily assemble and explode the ‘Radiological Dispersion Device’ (ROD) or Dirty bomb. This device will not produce acute radioactive contamination in the environment but creation of hoax of radioactivity to general public will be sufficient for terrorist’s aims.

Defence Laboratory, Jodhpur has developed “Mobile Nuclear Field Meter” for surveillance of the natural and artificial radioactivity released in the environment. This Is easily fitted in the  vehicle is suitably modified as per the requirement  in the field any weather conditions. In this vehicle various nuclear instruments viz. alpha and beta counting systems , air monitoring pump, gamma spectrometry system, hand held anemometer, contamination monitors, nuclear survey meters, Roentzenometer etc. were fitted for the measurement of radioactivity in different environmental matrices.

Very severe action will be taken by the authorities and it has been advised all the Head of the Vigilance department to co-operate with the officials during the time of action. If any Isolated Radioactivity material found in any area at the time of movements by the department.
