Hi wasnt sure where to post this... Does anyone know where I can get hold of free A-Level physics past papers and answers online ? cheers, Gus

It was a loooooong time ago !

This is a request for help from Mayor of Minami Soma City:http://www.youtube.com/watch?v=70ZHQ--cK40&feature=player_embedded Personally , despite the fact that radiation isn't off the scale in the city yet, I find it unbelievable the government isn't helping them especially after the IEAAs...

Unfortunately I only got to A level physics and Chemistry but basically you are saying that nuclear decay is a property of the nucleus ansd chemical bonding of the electron field around it ? Nonetheless it seems weird to me that the actual element could change due to alph/beta emision but the...

Is that because its mainly neutron imbalances that form isotopes and neutrons are not relevant to covalent and ionic bonding ?

Once it forms a salt is it still as radiocative ?

Has this already happened or is possible it will happen at Fukishima ? How much radioctive Caesium is there a portential to be released and what are the potential affects on the globe ?

Thanks.

Caesium has a low melting point but a high evaporation temperature. For this reason it should only be found locally after an accident such as Fukushima . Apart from explosions ejecting particulates high into the atmosphere how else is it that it can be found further afield ?

No answer to my last post ? Although I am not a nuclear engineer but this nuclear physisist seems to agree with my assesment :

According to some reports the spent fuel pool has 40 years of spent fuel rods stored there. Would that not be considerably more radiocative material than chenobyl ? So that's really what I would like - a slightly more technical answer. Lets assume that 40 years of fuel rods are stored there and...

I am aware of that - I live in Cornwall where there is several times the normal background level of radiation quite naturally. I am enquiring about the potential of this disaster to raise radiation levels above what are considered safe levels - globally. What I am looking for is an informed...

I might as well just spit it out : What are the chances of the entire world being drenched in dangerous levels of radiocativity as a result of this accident (on a scale of 1 - 100, 100 being likely ) ?

How likely is it that they can "properly moderate the pressure in the reactors" ? I was reading that the burning spent fuel rods release radioctivity as a gas and so it could get more or less anywhere.
