  • Update 15th March :-Security cameras installed by Israeli defense company at Fukushima plant have ability to detect presence of radioactive clouds in air.
  • The Arava-based Magna BSP company, which specializes in producing and installing stereoscopic sensory and thermal imaging cameras, had been contracted to place cameras around one of the plant’s six cores – the core that has been experiencing explosions and overheating.
  • Magna’s head, Haim Siboni, said the thermal cameras also had the ability to detect the presence of radioactive clouds in the air, but added that Magna had not been able to gain access to the images recorded by the cameras at this time.

Pentagon officials reported Sunday that helicopters flying 60 miles from the plant picked up small amounts of radioactive particulates — still being analyzed, but presumed to include cesium-137 and iodine-121 — suggesting widening environmental contamination.

Emergency flooding of two stricken reactors with seawater and the resulting steam releases are a desperate step intended to avoid a much bigger problem: a full meltdown of the nuclear cores in two reactors at the Fukushima Daiichi Nuclear Power Station. On Monday, an explosion blew the roof off the second reactor, not damaging the core, officials said, but presumably leaking more radiation.

Later Monday the cooling system at the number two reactor failed, Jiji Press reported — the sort of failure that preceded the explosions in the number one and three reactors.

Authorities have declared an exclusion zone within a 20 kilometre (12 mile) radius of the plant and evacuated 210,000 people.

The US nuclear-powered aircraft carrier Ronald Reagan, on a humanitarian mission to Japan, reportedly passed through a radioactive cloud from the plant and its crew received a months worth of radiation in about an hour.

There was no indication that any of the military personnel had experienced ill effects from the exposure, the New York Times reported citing unnamed government officials.

But the episode showed that the prevailing winds were picking up radioactive material from the crippled Fukushima plant, the newspaper noted.
