I have a camping stove that runs off methylated spirits and I need to buy fuel for it. Every American I ask has never heard of methylated spirits, or even anything like it. Read the Wiki description http://en.wikipedia.org/wiki/Methylated_spirit, where can I buy this in the US?

I was wondering if the plastic water bottles I drink from contain any chemicals released from the plastic. If you burn or melt plastic, there is a residue. Does this mix with the contents of the bottle? Seems like I can taste some chemical in Ozarka water and I was wondering if I was doing some chemical damage to my liver or something. It seems logical to assume that unless the bottles were washed really good, that there would be some residue from the molding process. Do they even wash the bottles before filling them? Anyone know?

I hope someone can show me how to work out these problems step by step. I am having trouble with my chemistry homework.
The quetions are:

At 3.00 m from a radioactive source the intensity of its gamma radiation is 202 roentgen. How far away would we need to be to reduce the intensity to 4.64 roentgen.

At 2.00 m from a radioactive source the intensity of its gamma radiation is 522 roentgen. What is the intensity at a distance of 37.8 m?

I would appreciate any help.
