Model T Ford Forum: Forum 2015: OT Firestone Polonium Spark Plugs

I purchased a few years back a "lot" of Model T parts. And in that lot came what I thought was Model T spark plugs. I recently went to use them, but they are just a little too small. They aren't even the right threads. I have 18 Firestone Polonium M-60 and 21 M-80 plugs. NOS in the box. I know about the Polonium "gimmick". But curious if anyone knows what they would be used for. Is the "M" for Motorcycle?

Can't answer your question but here is a past thread on these that fit Model T.

I wouldn't carry one around in your pocket if I were you.

That's the same advice I give to people about Coleman lantern mantles. The material that remains after the silk (or whatever it is that has now replaced the silk) burns away is phosphorus and is a low-level radioactive compound.

It's also a good idea to wash you hands after you're done changing a mantle.

My T Speedster has had Polonium plugs in it for over 20 years. They seem to be good plugs.

I second Mike's warning, here is what Wikipedia has to say about Polonium:

The radiation you get from one x-ray is equivalent to carrying one of those plugs in your pocket for around 100,000 years. The same scare is used for thoriated TIG electrodes. I have a pack of old ones and they don't even register on my hand held meter.

I've had a set of those spark plugs glowing over in the corner of the shop for a couple years. It hasn't seem to have had a negative affect on anyone around here other than the 47 pound rat with the horse hoof growing out of its nose.

They have a nice purple radioactive color about them. You can put one in your egg carton to kill all of the nasty bacteria!

LOL... You get more radiation from the sun while you're mowing the lawn. No one has outlawed that ... yet.

Thanks Ken for bursting the one dream I've had for all those years. Hopefully that law is up for review.

I am not going to look it up but I would bet a Dr. Pepper that iodized table salt would give you a bigger dose of radiation than an 80 year old Firestone Polonium plug.

There are about 4 standard sizes of straight thread plugs; 7/8" (Model A and other cars/trucks/tractors 20's 30') 18MM early V8's, 14MM most everything, 12MM(?)for small engines, then you can get really small ones for model airplanes. I am sure that's not all but off the top of my head the usual suspects.
Did a quick Google search on the M60's, thread in photo looks about 7/8".

For what it is worth the glow in the dark Firestone Polonium plugs that fit a T are numbered E-100-F. DO NOT BUY THEM!

Why not?

I've got a full box of them they are NOS, should I incase these in a lead box..? Or gift them out to my model T buddies I don't like ?
First set I bought I carried around a show / swapmeet for 4-5 hours I've now had 13 melanomas removed from my body is there a correlation?
Oh well looks like I doomed....!
These ran great in my T they are a nice deep pink color, never had any issues with them, now there might have been some radio active exhaust escaping out the back but at 35-40 mph I was out running running the threat..... I think? LOL
