Its no problem, for me its too late as i have been exposed so only time will tell if i keel over, if so then i will get the missus to write a follow up post about my post mortem

like i said earlier i am inquisitive its my nature, it was not my intention to put noses out of joint, frighten, or even make light of the subject, more me being objective than anything. I had made some perfect repro Mk1 dial faces (12) which were all specially printed transfer onto laser cut blank discs...... they will sit on the shelf now unless folk have mk1 gauges with busted faces....... Kev any chance you could take a Mk1 dial to work and check that for potential contamination ? The thread has pretty much bottomed out the Mk2 as being dodgy ground, it would perhaps be a nice add on to know the ins and outs for the mk1 gauge who knows perhaps a data sheet could be put on its own thread listing dials from specific vehicles which contain the radium 226 so people have a heads up before climbing into range wrecks or potential restoration projects

here is a medical write up regarding exposure and ingestion, for me it put things into more realistic terms

When you said you were converting a MK2 gage To a MK1 I really got xcited as My MK 2 has a gage with the glass broken in it, by some kids before I got it.The broken glass is still in it . This has been a great site to enlighten us on this problem . Now what to do ? How to handle this gage to remove it ? PS Do you know that if you ate a banna be for you go to work in a Nuclear Plant you will set off the alarm .

after the shooting stopped in gulf war 1 it was my task to go around kuwait collecting up the iraqi armour and take it to a collection point. some of the shot up stuff was covered in a gunmetal grey dust which i later found out was depleted uranium

me and the reccy mech were covered in the stuff and i'm still alive and kicking but i do sometimes wonder if it will catch up with me one day.
it was a good laugh though

rick

ps. thanks for bringing this to light, it never even crossed my mind that there would be a problem with handling old instruments. cheers

well......... I have a load of mk1 dial faces for those with knackered Mk1's or for folk that have access to correct sealled cabinet units to convert Mk2's

Just need kev to confirm what the state of play is with the Mk1 gauges....or anyone with access to a counter for that matter ?

the problems are as discussed above George, the Dr I spoke to offered a method but people need to understand that there are risks involved and as Kevin has said he deals with this stuff on a daily basis.. make an informed decision before doing anything, the main issue is with particle inhilation / ingestion i copied a link from a medical professor regarding absorbtion rates etc etc have a read !

Now then.... on Ricks thread a very good point was raised, what needs to happen with the information now is to educate people rather than create hysteria, the UK government for example have a knack of having knee jerk reactions to stuff and going OTT on dealing with it....what we dont want is folk having thier gauges ripped out of trucks etc and being ordered to dispose of them due to them being radium luminised.

My gage has been cracked for probably 40 years . The question now is How much radiation is left and is the whole gage contaminated .Can it be redone up with a new dial and glass without hurting someone .If this can't bedone then is it even safe to remove it without some protective gear .

RichardT10829 · #36 30-10-12, 20:27

the gauege will be thoroughly contaminated mate, the three small segments and needle tip are the bits that were luminised, you might be able to find somewhere to fit a dial face for you the problem is the dust being spread about... where is the gauge now ? if its in a box along with oher stuff i guarantee you everything in the box with the gauge will also be contaminated too..

in my humble opinion in your case i would at very least wear rubber gloves paper suit and respirator to handle the gauge with a broken glass face (not dismantle it) but the rubber only stops you getting particles on your hands and nothing more

the dial face could be done by someone i am sure but they would need a propper purpose built cabinet to put the dial into which was sealed and behind glass etc etc the dial face itself comes out with two screws the needle slides off..... thats easy.....just not easy to do without getting a dose or contaminating your workshop etc etc.

The gage is still in the instrument panel on the carrier .I could duct tape the front to contain the dust and then remove it for disposal .I don't know how many guys have looked at this gage over the years . I have a box of gages for a halftrack ,wonder if they are the same problem too .

RichardT10829 · #38 01-11-12, 09:42

George. wear a mask and gloves at the very least... possibly a good idea with the tape... do you have any spare glass fronts to replace the broken one out of curiosity?

Lynn Eades · #39 01-11-12, 10:18

If you had a Mk I* speedo (see attached picture) I think they are completely safe. My guess is that they relied entirely on the panel light
I dont think there is any "luminous" stuff in there. Maybe the radium paint in the MkII* is the result of comlpaints about not being able to see the MkI* speedo at night.
With your MkII*, maybe it would be better to buy a nos one, and dispose of the old one. What ever you do, be careful.

I have a new speedometer for the MK2 but when Richard said he could make a MK1 out of the MK2 I thought great idea but then this problem showed up .Is there away of decontaminating the radium Water eg.? I have seen alot of carriers with broken gages and not once thought about radiation I would need the different dial and the glass for a MK1 tochange it
