Nuclear Radiation, Japan Secure Visited

Although nuclear reakor in Japan reportedly suffered damage following the earthquake on Friday last week, sunrise country was still safe to visit.

The view was expressed by members of the National Energy Council which is also the Dean of the Faculty of Engineering, University of Gajah Mada in Yogyakarta Tumiran, Wednesday evening (16/03/2011).

Tumiran said the government should not issue a travel warning for Indonesia people who want to visit Japan. "To this day radius of the radiation is still only a few kilometers only, and not all Japanese territory affected," said Tumiran.

Tumiran explained, the damage is still a leak, and the Japanese government still continued to make efforts to cool a nuclear reactor in Fukusima. The time needed to perform cooling is very dependent on the condition of uranium fuel used.

"If uraniumya are new, for cooling may take up to 1 or 2 years. But if you live the remnants of uranium, in a matter of days or weeks may have been successfully cooled reactor," he said.

Based on information obtained Tumiran, radiation exposure due to leakage of the reactor reached 400 milisievert Fukusima per hour. "Never mind the 400 milisievert per hour, 100 per hour milisievert alone is cause serious harm to human health," said Tumiran.

This figure far exceeds the threshold of radiation that can be tolerated by the human body. Ordinary human body is only able to receive radiation exposure of 0.15 per hour or 35 microsiever milisiever per year. Meanwhile, for workers who used to work at a nuclear reactor, which can be a little more resistant to 50 milisiever per year.

The impact of radiation exposure to the human body, according to Tumiran very complex, in addition to burning the body, also can damage body cells and the effect on the composition of human DNA.

"Apart from a sense of sympathy and sorry for the Japanese society, people in Indonesia need not worry because the radiation radius of only a few kilometers from the reactor
