Some scientists say Fukushima is worse than the 1986 Chernobyl accident, with which it shares a maximum level-7 rating on the sliding scale of nuclear disasters. One of the most prominent of them is Dr Helen Caldicott, an Australian physician and long time anti-nuclear activist who warns of "horrors to come" in Fukushima.
Chris Busby, a professor at the University of Ulster known for his alarmist views, generated controversy during a Japan visit last month when he said the disaster would result in more than 1 million deaths. "Fukushima is still boiling its radionuclides all over Japan," he said. "Chernobyl went up in one go. So Fukushima is worse."
On the other side of the nuclear fence are the industry friendly scientists who insist that the crisis is under control and radiation levels are mostly safe. "I believe the government and Tokyo Electric Power [Tepco, the plant's operator] are doing their best," said Naoto Sekimura, vice-dean of the Graduate School of Engineering at the University of Tokyo. Mr Sekimura initially advised residents near the plant that a radioactive disaster was "unlikely" and that they should stay "calm", an assessment he has since had to reverse.
Slowly, steadily, and often well behind the curve, the government has worsened its prognosis of the disaster. Last Friday, scientists affiliated with the Nuclear and Industrial Safety Agency said the plant had released 15,000 terabecquerels of cancer-causing Cesium, equivalent to about 168 times the 1945 atomic bombing of Hiroshima, the event that ushered in the nuclear age. (Professor Busby says the release is at least 72,000 times worse than Hiroshima).

Economic cost
Fukushima: Japan has estimated it will cost as much as £188bn to rebuild following the earthquake, tsunami and nuclear crisis.

Chernobyl There are a number of estimates of the economic impact, but thetotal cost is thought to be about £144bn.
Safety
Fukushima: workers are allowed to operate in the crippled plant up to a dose of 250mSv (millisieverts).
Chernobyl: People exposed to 350mSv were relocated. In most countries the maximum annual dosage for a worker is 20mSv. The allowed dose for someone living close to a nuclear plant is 1mSv a year.

Death toll
Fukushima: Two workers died inside the plant. Some scientists predict that one million lives will be lost to cancer.

Chernobyl: It is difficult to say how many people died on the day of the disaster because of state security, but Greenpeace estimates that 200,000 have died from radiation-linked cancers in the 25 years since the accident.
Exclusion zone
Fukushima: Tokyo initially ordered a 20km radius exclusion zone around the plant
Chernobyl: The initial radius of the Chernobyl zone was set at 30km – 25 years later it is still largely in place.

Compensation
Fukushima: Tepco's share price has collapsed since the disaster largely because of the amount it will need to pay out, about £10,000 a person

Chernobyl: Not a lot. It has been reported that Armenian victims of the disaster were offered about £6 each in 1986
Aid
Fukushima: The UN's Office for the Co-ordination of Humanitarian Affairs reported bilateral aid worth $95m
