    I do not wish to get into a bun fight over the issue of radium lume safety but I have to correct you, dear AbingtonLad. Radium not only emits alpha particles, but also beta particles and gamma radiation. It is true that the major danger with radium lume, as I have often pointed out, comes when watch enthusiasts start messing about with old radium lume on their old watches, with the risks inherent in touching, inhaling or ingesting radium, even in very small amounts. Radium lume should therefore be treated with respect. In terms of a health hazard from a radium source when it remains outside the body, it is the beta particles and gamma rays that pose the real threat, and of these two forms of ionising radiation, attenuation by storing watches carefully and away from the body is easiest to accomplish in the case of beta particles, which are generally blocked by a solid object.

    The point about radium lume for watch collectors is not that we should all panic and get rid of our old lumed watches; it is just a question of common sense and a bit of science - plus an understanding that it has now been shown that there is ultimately no "safe" threshold for radiation.

    :)

     

    Dear Aw,

    My wife has a PhD in Nuclear Physics (with a specialism in radiation in medical imaging) and is head of radiation safety at a number of hospitals across Cambridge, Suffolk and Essex... if you'd like to argue the point with her, be my guest!!

  2. I think there are several previous threads along these lines still on the forum. I always contribute as my wife is an expert on radiation and knows the reality behind the 'problem' of lume, especially radium.

    So radium... it decays by emitting alpha particles, which are energetic (and therefore potentially dangerous) but only over a VERY short range. The average alpha particle emitted by radium will only travel a few millimetres before being absorbed by some other material, such as the case of a watch. In fact tissue paper is strong enough to act as a barrier to alpha particles. 

    Very few - if any - of these particles will ever make it out of the watch and into your wrist.

    The poor women who died from using radium did so because they had a habit of licking the paintbrushes they were using to apply the radium, in order to keep the bristles in shape. This meant that large amounts of radium were ingested into, and came into direct contact with, the soft, delicate tissues of the throat, stomach and intestines. This, inevitably, led to the various cancers which caused their untimely deaths.

    So, in short, there is nothing to worry about. Nothing whatsoever.

    Nada!

  3. Hmmm... how is it that none of the 'gold' Seiko Retros exist in the UK, but loads are available from the US?

    Did Seiko direct all the (slighfly) bling version straight to our friends over the pond, or did our liberated cousins voluntarily snap up anything with a golden glint, only to decide they would be better off filtering them back to us, gradually, surreptitiously... at far more than we should be paying? (Once you include import duty, etc etc).

    These things bother me.

  4. My personal experience isn't good. A liver test six months into treatment showed that I needed to stop taking statins immediately, as they were causing muscle damage (which, if unchecked, can be fatal).

    The official statistics for this kind of side-effect talk about 'a few cases per million', but I am aware of five people that started them roughly when I did, and two of us had severe complications. Of the remaining three, only one still takes them. The other two had lesser complications, but still sufficiently unpleasant to halt treatment.

    As you say, when assessing the glowing reports for these drugs, it's important to ask who benefits the most from them being prescribed. An interesting aspect to this is 'Number Needed to Treat' (or NTT), a statistic which indicates how many people need to take a drug, over a specified period, for the drug to achieve its designated goal. In the case of statins, a 2015 article in the Journal of Cardiovascular Medicine revealed that, at age 50, 1000 men would need to take a statin for 5 years (at a cost of more than £200,000) in order to delay one death.

    Obviously you need to make your own decision Mike, but ask for specific NTT figures for the suggested treatment and be very alive to the chances of an adverse reaction, should you decide to go ahead.

    P.S. Various industry studies have shown statins to be one of the five most profitable drugs ever produced. Just putting that out there...

    If you want the old timey experience from Olympus, then you'll like the look of the PEN-F. The biggest drawback being the large pile of cash it takes to get one. :wink:

    Holy Cow they go for big bucks!

    Had a very generous offer from a forum member on a Sony SLR digital, but still struggling to make a decision. There seem to be quite a few models and variants of the PEN - just stumbled across the 'mini' range, which might do the trick. Or not.

    My head hurts :wacko:


  6. Sorry to jump on your thread Mr Bond, but I too am looking for a half-decent digital, mainly to take pictures of flowers and the like (ah!).

    But me being me, I rather fancy the idea of picking up and old Olympus Pen E-P1 (or maybe 2...).

    Am I bonkers? I had a lovely Olympus Trip when I were a lad, but it ended up in a ravine in what is now Croatia. I kind of miss it, and am a bit of a sucker for the retro look.

  7. That case looks cracking - and even better (nearly) full of Seikos :thumbsup:

    Out if interest, has anyone ever come across a solid aluminium case that works well for watches? I spent ages researching options on eBay, then managed to get one that has compartments too small for the majority of my watches (which average around 43mm).

    I need something solid as it'll be doing a fair amount of travelling in the not too distant future, and clear - especially glass - lids are not terribly practical for that kind of activity.

    Any advice would be greatly appreciated. And no, I can't just put them in socks... or can I?

    Still Paul & Sharking it today

    :laugh: :laugh:

    Anybody know how to make a bag of sh!te IPhone take colour picture again. The thing is driving me to distraction !!!!!

     

    In the camera window there should be three interlocked circles at bottom left - click on these and then choose 'none' from the range of filters that then appears.

    If this doesn't work, I'm afraid you are permanently stuck in 1957.

  9. Forum member JonW is 'Mr Deskdivers' though sadly he hasn't been around for quite a while. I think he's seriously busy with Deskdivers, books, work... and who knows what else. But he's a top bloke.

    You could try mailing him for some info on the 120 Chronometer - if he can't give you what you need, you aren't going to get it!

  10. I think you'll find that the "Waterman's" that make the watches has nothing to do with "Waterman" of Paris, the company that make pens.

    Not so sure Mike... it's not entirely clear, but there is this passage from an advert for a 40s gold 'Rolex' style watch on t'internet:

    Founded in 1888 by Lewis Edson Waterman, the L.E. Waterman Pen Company was the gold standard for fountain pens until World War II, when its popularity waned. Although not believed to be corporately related, this vintage men's Waterman watch lives up to the same lofty standards as those highly collectible pens. According to the US Horological Trademark Index, The Waterman Watch Co., Ltd of West Orange, NJ registered with The US patent and Trademark office in July 23, 1943. The round 29mm case is crafted from solid 14k yellow gold and still sports a highly polished condition...

    So there would seem to be a connection and something of a pedigree - they are not quite the 'Johnny-come-Latelies' they first appear to be. Though what exactly 'corporately related' means in the above extract is beyond me...
