Hi Jim, I've performed work with Battelle Centers for Public Health Research & Evaluation and this very matter has been studied to record and verify every statement I've offered. 73's Richard Clark, KB7QHC Well, I used to play with blobs of mercury a lot when I was a kid and it has never eeefffffecttted (snort)mmmmeee a (slobber) biiiittt. Good one, JJ! 8^) Mercury isn't very harmful by that route of exposure. You could polish quite a few dimes if you like, and not suffer much if any damage through skin absorption. But! Inhaling the fumes is another thing entirely. Mercurey poisoning has been known about for a long time now. Daggureotypists in the early 1800's often suffered from mercury poisoning as they purposely fumed the image plates to develop the images, producing a silver amalgam on the surface in accordance with how much it had been exposed to light. A beautiful but deadly process. The feltmaking process used to use mercury as a preservative, and the saying "mad as a hatter" was coined for a reason. And yet we still have people today that think that caution in handling mercury is some kind of "liberal" plot or something. - Mike KB3EIA - |

Holding it in your hands is more of an issue if A) you have some sort of wound, and some could contact your bloodstream, or more likely B) if you do not _thoroughly_ clean it off your hands before touching food, rubbing your eyes, smoking a ciggie, etc. Happy trails, Gary (net.yogi.bear) ------------------------------------------------ at the 51st percentile of ursine intelligence Gary D.

The later two have a monomolecular air/water interface - the Langmuir layer. The decay products of nuclear breakdown (the electron emission) is no hazard due to its inability to puncture the dermal layer - inside the body it leads to chromosomal breakdowns that gives rise to cancerous growths. Same vector, two different paths separated by lack of caution in the errant belief about exposure levels leads to grief.

Which proves nothing except that you went to a seminar.

Well, I gave an answer, farther down the thread, that actually is more
on subject, liquid antennas. I told him where to find a group that knows about them and builds lots of them, which is more than anyone else seems to have done. Looks to me like most of the regulars on this newsgroup, except Roy and a couple others, talk about anything except the subject/question that started the thread. Which is their right. Just don't get annoyed if I point out that fact occasionally. Also the fact that anyone with an IQ above room temperature knows mercury has to be handled with some care. tom K0TAR Richard Clark wrote: On Wed, 21 Apr 2004 22:12:51 -0500, Tom Ring wrote: Hi Tom, Then we can both agree that I speak from a point of knowledge (got the experience too).

That doesn't mean you ignore the hazards or go screaming in terror just because you see mercury. -- Jim Pennino Remove -spam-sux to reply. |
