Is chorine radioactive

Answer 1

Farming or any other type of agricultural industry would be dangerous and completely inappropriate for at least 200 years. It will be at least two centuries before there is any chance the situation can change within the 1.5-mile Exclusion Zone. As for the #4 reactor where the meltdown occurred, we estimate it will be 20,000 years before the real estate will be fully safe. Randall Bell - http://www.strategy360.com/

Answer 2

Yes.

It's well documented online that the Chernobyl disaster has rendered Pripyat and surrounding areas uninhabitable for centuries.

Answer 3

The Chernobyl Disaster was the result of really bad engineering and negligence.

First of all the Soviet RM-BK type reactors had a severe design flaw.

Positive temperature co-efficiency. This means that if the reactor core temperature increases the Neutrons will start to excellerate which in turn creates more heat.

Also reactors containing Graphite moderators are illegal in Europe and the United states for this exact reason. Also the control rods were tipped with graphite, this means that if any control rod gets stuck while re-entering the core the graphite between the control rod tip and the top of the moderator would start to attract neutrons toward the top of the moderator, and the neutrons would begin moving between the rods and the moderator instead of inside the moderator, this also means the reactors core temperature would increase phenomenally fast and the operators would lose control of the reactor VERY fast. The speed of the neutron count and density reached the energy equivalent on TNT (Tri Nitro Toluene) this is when the explosion happened.

Many people have asked why wasn't there a thermal explosion ?

After the initial explosion most of the energy in the reactor core was dispersed during the explosion and when the UBS (Upper Biological Shield) was blown from the reactor most of the neutrons were propelled out of the reactor as well as chunks of the moderator. After this happened the chain reactions stopped because the neutron density was no longer sufficient to sustain nuclear fission.

If this melted nuclear material had come into contact with water, the water would act as a moderator and this could lead to a runaway chain reaction that would result in a thermal explosion.

Answer 4

Decommissioning work on reactors 1 to 3 is ongoing, and a new more complete structure is to be built over the destroyed reactor 4. The following extract from www.world-nuclear.org gives a more complete diew of what is happening at Chernobyl.

Four Chernobyl RBMK-1000 reactors, plus two almost-completed ones, are being decommissioned. Unit 4, which was destroyed in the 1986 accident, is enclosed in a large shelter and a new, more durable containment structure is to be built. This shelter project will be funded by the International Chernobyl Shelter Fund facilitated by the EBRD and is expected to cost about EUR 700 million, all of which has now been pledged. In September 2007 a EUR 430 million contract was signed with a French-led consortium to build this new shelter, to enclose both the destroyed Chernobyl-4 reactor and the hastily-built 1986 structure over it. It will be a metal arch 105 metres high and spanning 257m, which will be built adjacent and then moved into place. In May 2005, international donors made pledges worth approximately EUR 150 million towards the new confinement shelter. The largest contribution, worth more than EUR 130 million, came from the G8 and the EU. Russia contributed to the fund for the first time and other fund members, which include the USA, increased their contributions, with the Ukrainian government pledging some EUR 15 million. The European Commission has committed EUR 239.5 million since 1997, making it the main donor. Units 1-3 are undergoing decommissioning conventionally - the first RBMK units to do so, and work will accelerate when the new dry storage facility for fuel is built (see Waste Management above).

Answer 5

Chernobyl was the site of the worst nuclear accident in history. The area still has dangerous levels of radioactivity associated with it, and will for years to come. The radioactivity can cause a number of different diseases, and can ultimately kill people.

Answer 6

Only a trace of environmental chlorine (of the order of one part in 10-13) is the radioactive isotope 36Cl. If you wish more information please see the wikipedia page about isotopes of chlorine.

Answer 7

It is located south of Pripyat on the Pripyat River in North Central Ukraine. It was the site of the worst nuclear power plant disaster in history.

Answer 8

Yes, after the 1986 (April 26th) disaster (highest level on the 7-scale) it has polluted a wide area with radioactive material deposit of all kinds.
