Japan and its issues

Today, i will be discussing 2 very interesting issues in Japan. firstly, japan instructed local authorities on Thursday to start screening food for radioactivity after accidents at an earthquake-hit nuclear power plant sparked fears of wider contamination.

It is the first time Japan has set radiation limits on domestically produced food, a health ministry official said.

The limits are in line with an anti-disaster programme prepared in advance by the government's atomic power safety commission, said the official.

Limits vary depending on the type of foodstuff but have been set in consultation with internationally accepted levels and average intake in the Japanese diet.

Radioactivity leaked into the air after explosions at the Fukushima No. 1 plant, where last week's quake and tsunami knocked out the reactor cooling systems.

Several Asian nations have said they will screen food imported from Japan for radiation while the European Union has called for similar checks.

HELICOPTERS are dumping water on a stricken reactor in north-eastern Japan to cool overheated fuel rods inside the core.

The crisis at several reactors of the Fukushima Dai-ichi plant were set off when last week's earthquake and tsunami knocked out power needed for their cooling systems and ruined backup generators.

Japanese officials struggling to avoid full meltdowns have raised hopes of easing the crisis, saying they may be close to bringing power back to the plant and restoring the cooling systems. The top US nuclear regulator warned that one reactor's cooling pool for spent fuel rods may have run dry and another was leaking.
