Oh ya....you have strontium 90 in those old watches who's hands glowed in
teh dark too!

Hee hee....funny you should mention that, Bruce......

Ol' Larry whips out his radiation counter from a nearby bin, passes it
over the tube guts and declares it non-radioactive....sweeps it up and
dumps it in the sh!tcan.....(c; /
I didn't have the heart to tell him NONE of the tube PARTS is
radioactive....just the gas that WAS in it before he broke it. The
gas was gone so it was a non-issue.....(c; /
I don't know where NAV gets these crazy, paranoid ideas.....(sigh)

Larry, very funny story! ...but not at all accurate w/r to detection of
radioactive material, the type and emissions of which your "geiger counter"
was never designed to detect.

While we could have played similar games with inspectors, the weapons and
propulsion engineers that inspected my old missile submarine would probably
have missed the humour. ;-)

And the R or reverse polarity ones. I must admit I replaced a few of those
with the normal ones and lost a few more hairs from my now bald head trying
to figure what the new problem could be.

Most of the 1N415x series had reversable bases, so one can have both
polarities with one product.....

Which type of emissions is that? The Synctillation counter I had was
the same one used on nuke subs at the time. Are there quarks or
exotic isotopes of Cornucopium radiating from plain old thyratrons??


Our ship was powered by sweat and bunker C oil you had to boil before
you could spray it into the 1945 boilers. We had some clocks with
radium dials, though...(c;

They were slightly radioactive, even broken, but not so much that any
"geiger counter" could detect anything. We used instrument hundreds of times
more sensitive on submarines, and measured air, urine and swipe samples for
alpha, beta and gamma detection, accordingly. Some of those processes
involved superheating the pressurized samples in equipment that detected
levels to small to be discussed. And of course we wore two different types
of personal-detectors, according to the area of work performed on the boat.

As to disposal of broken tubes, even today, your method seems acceptable to
everyone except the frantic and frustrated emergency drill inspector, who
I'm sure never forgot you.

FAA radar tube disposure methods: I had a good laugh when I saw your idea
here ;-)

(1) Handling. There is no external radiation hazard due to normal handling
of radioactive electron tubes.

(2) Storage. Exercise judgment and caution to avoid large quantity storage
and possible breakage. Under no condition shall random storage in boxes or
bins be permitted. All storage areas for large quantities of radioactive
tubes, such as the FAA Depot, shall be clearly marked with radiation warning
signs as described in paragraph 24.d.

(3) Decontamination. In the event of breakage, decontamination shall proceed
as follows:

(a) Dust. Avoid agitation of dust in order to minimize dispersion of the
radioactive material. Internal exposure by ingestion and/or inhalation
should be avoided. Should either or both occur, contact the cognizant
Aviation Medicine Office.

(b) Tube Fragments. Retrieve tube fragments with forceps or pliers and
dispose of them as normal waste. Clean instruments with a dampened cloth. If
forceps or pliers are not available, use gloves and dispose of them
immediately after use. Do not handle tube fragments with bare hands.

Back in the 1960's, Moravia Central School (Moravia, NY) had an
NRC-licensed tiny Cobalt 60 source kept in the school safe in a
lead-lined box our physics teacher, Mr Dewey, used to use as a source
to irradiate all the Junior classes.

Mr Dewey was an old WW2 B-17 pilot who could tell us fascinated kids
some real war stories of bombers and Germany. He had the schrapnel
scars and Purple Hearts to prove it. The other fascinating thing he
had was his flyer's radium-dial wristwatch, which was so "hot" he had
to put it in the lead-lined box so you could detect the radiation from
the NRC-licensed Cobalt 60 source.

Mr Dewey died of old age, not from the burn spot on his wrist from the
Gamma rays coming through the back of that watch. His arm looked
slightly sunburned around the watch, but was still darker color right
through the back of it.....

I'll never forget all the great things he taught me in physics and
chemistry....over 40 years later.

A quick overview of Radium dial-painting can be found at:

And here's a set of pictures of luminescent products. Wow, glow-in-the-dark
buttons!

Clearly, it was more hazardous to make these items than to use them.

Wow, I'm always amazed to hear stories from 'back in the day'.

The tools they gave us back in the day that we find today to have
been...well...not all that healthy.

Like the troops using depleted uranium shells....or the cops that didn't
think much when they set their radar guns in their laps!
