Japan's National Police Agency will introduce radiation-proof vehicles as part of stepped-up counter-terrorism measures at nuclear power plants.
The agency says the new vehicles will be installed at 9 police headquarters in the country. The vehicles are shielded with lead, which blocks radiation.
The vehicles will enable police officers to protect themselves from radiation when apprehending terrorists and rescuing the injured in cases of terror attacks or accidents at nuclear plants.
In the wake of the September 11th attacks in the United States in 2001, Japanese police have been guarding some of the country's nuclear plants and related facilities. Armed officers and bullet-proof vehicles are on duty around the clock.
Agency officials say they are stepping up counter-terrorism measures in the belief that the accident at the Fukushima Daiichi plant has increased the likelihood of nuclear facilities being targeted.
