Is Chernobyl reactor 4 still burning?

Early in the morning of April 26, 1986, the fourth reactor exploded at the Chernobyl nuclear power plant in Ukraine. 34 years later, Chernobyl radioactivity is still circulating. They are now the biggest fires ever recorded in the Chernobyl exclusion zone. …

20,000 yearsGauging the risk. The ruins of the Chernobyl reactor, now contained under a metal shell, are still highly radioactive and will likely remain so for up to 20,000 years.

What is the highest radiation level?

According to the National Institute of Radiological Sciences, exposure to a mere four sieverts of radiation would typically be lethal for one out of every two people. The highest level of radiation detected previously at the Fukushima reactor was 73 sieverts per hour.

What’s a dangerous level of radiation?

To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite risk of cancer and other diseases.
