Maybe your dumping caused a mutation that evolved into a new life form?

It happens in movies :p

Nah, the authorities probably scooped it up and put it back in storage, the same storage that payed me to take the stuff 10 minutes earlier...

BTW, Is D2O really a worse radiation shield than H2O?

Of course I have to give you the weasel answer. Depends on what you mean by radiation shield? I am assuming from this thread that we are speaking of atomic radiation. By shield do you mean blocking totally or moderating (slowing down)?

As for blocking:

Alpha particles and Beta are blocked very well by water. Gamma radiation not so well. X-ray not so well. Neutron particles (radiation) very well. I am not sure of any significant (another great weasel word) changes between H2O and D2O for these radiation types.


As for slowing down:

In reactors Neutron particles are slowed down by water and D2O does a "better" job than H2O in slowing down the neutrons so that more have a chance to cause fission.

I thought Alpha radiation was very potent if you manage to take it into your body, but was blocked by most things?


You are correct. Alpha Radiation is the most toxic per amount and you are correct that it is blocked by pretty much anything as it is a particulate.

IIRC Alpha radiation can be blocked by a sheet of paper. Can't remember where I saw that though. :hmm:

Unfortunately ignorance radiates through all barriers. I would identify that as the greatest problem.
