Hi

Another lamp to use is a GERMICIDAL type. It is also refered to as
disinfection lamp. It emits a short-wave ultraviolet radiation with
peak at 253.7nm. It is used for killing viruses, bacteria etc. I have
been using one for general EPROM erase and ST62XX wiping. A few
seconds and its all gone. From time to time I leave it on in my
caravan and sweep out the dead bugs afterwards. It actually smells
clean afterwards. SO, use a germicidal tube and  *kill two flies with
one stone*

Regards
CC

Will it kill the bugs in my programs?

If I'm not mistaken, then UV (with high enough frequency) causes the
formation of ozone.  That is probably what causes the 'fresh smell'.
Now, before we all switch on our UV erasers in an effort to save the
ozone layer, I've also heard that ozone is poisonous.  I'm not sure
about that though, but in the least, it irritates your airways.  I once
forgot my homebrew UV eraser on overnight and felt really bad the next
day.  Since then I have constructed a small timer (with a PIC of course!)
to prevent such incidents in the future.

I am impressed by the speed with which your lamp erases EPROM's.  Where
can I get such a lamp?

Yes, ozone _is_ poisonous.  I remember about 15 years ago everyone with
allergies was advised to install an electrostatic air filter on their
furnaces since these devices do a great job of removing tiny particulates
that conventional filters can't touch.  Well, after a few years of real
world experience, it was discovered that the ozone produced by these
devices was more irritating to those with allergies than the particles they
were removing.

I believe ozone is O3, compared with oxygen, which of course is O2.  Any
thing which can impart the energy to the O2 molecule to cause it to bind to
another oxygen atom can create ozone.

BTW, photocopiers and laser printers are great sources of ozone, especially
if they are poorly maintained.

It's a fairly aggressive oxidant, I would'nt recommend breathing it
instead off normal oxygen (ozone is 3 atoms of oxygen, 'normal'
oxygen 2)

Properly designed ES filters don't do this - if you can smell ozone -
its a bad one.  BTW, you can smell it way before its toxic - pity
something that smells so nice is toxic...

Ozone can elicit an allergic reaction long before it is noticeable, or toxic.

   Ozone is not a good thing at ground level, it is one of the sources of
smog. In the upper atmosphere it is a good thing. TTYL

Hi

Do you have a specific brand name, availability (where, $$?).

Thanks

       Absolutely.

       The clean smell is ozone.  One doesn't want to breathe too much of
this, however, because it is toxic.  It is O3 or oxygen with an extra atom
in the oxygen molecule.  It decays back to O2 and the lonesome oxygen atoms
send spams over the Internet and find other recently divorced oxygen atoms
to pair off with.:-)

       Here in the United States, ozone is used to flood railroad cars
filled with produce since it is good at killing varmants, but non persistent.
It is also used in place of chlorine in some city water plants to kill things
so the bottom line, here, is be careful.
