I still would like to see something that says that IR causes cancer. I know UV causes it. Could it be that you are getting these 2 mixed up? I did a google search and couldn’t find anything. IR will cause the burn if you use it too long, but it is the UV that causes the cancer.
Anybody else have any info on this?
IR and cancer? I’ve never read or heard anything to that effect. UV certainly, but IR is something that is used as a therapy for healing. The only connection I could imagine is that it helps speed metabolism, so any existing cancer may get a helping hand, maybe. That’s a real long shot guess off the top of my head though.
I’m going to go have a look now to see what I can find because it’s too important to ignore.
As for the tadpoles, if you are in any doubt and if it matters to you, then a £15 microscope from Aldi (or whatever the equivalent in your country is) will provide you with an indisputable answer. Before you take that route though, be sure you know what you’re getting into. You might develop some rapport with the little critters upon first sight, and start to feel guilty in shooting them out into the great cold abyss.
For IR burn, if you use an IR pad you can circumvent that one as they emit only at specific and useful frequencies, whereas bulbs have a very wide spectrum output.
