    ** Nonsense - the x-ray attenuation factor of thin Fe-Ni alloy is small.



    ** Wiki disagrees.

    You got a cite for that ?



    ** Maybe so, but the face glass is way thicker.


    ** You must be desperate to use survey crapology as evidence.


    ** Irrelevant to the point - fool.


    ** When ???

    It ain't changed.

    I recently went to a lecture by Jim Thurston, Medical Engineering and
    Physics, King's College Hospital, London; mainly about hormesis and
    background to the polonium murder of Litvinenko in London.

    But at the end I asked for an explanation of something that has always
    evaded me. Why some incinerator plants are licensed to incinerate low level
    radioactive waste , as it gives the impression that you can rid radioactive
    material be incineration, compared to landfill.

    The answer, from that government scientific advisor, was along the lines
    that a lot of it is for the purpose of incinerating biological hazard
    material that is also radioctive.
    Then it is a matter of distributing the plume of radioctive outfall , from
    the smoke/gases, over as wide an area as possible, of adjascent
    communnities.
    It is some sort of ststistical exercise. Too much radiation per Kg then it
    cannot be allowed to be dumped but if the radioctive component from that Kg
    is distributed over some (unspecified) large area of land surface then that
    is permitted.

    So that about says it, doesn't it ? 'Official' government advice from
    someone that you would expect better of, based on what you would have to say
    was at best, 'dubious science' !! It defies belief, but goes a long way
    towards explaining to 'eco-believers' why things such as lead-free solder,
    are actually nonsense ...

    You clearly know nothing at all of Europe or its politics. If you seriously
    believe that the UK is responsible for bringing about ANY Europe-wide
    legislation, you are very seriously deluded. All Eurobollocks is driven by
    the likes of France and Germany, and our emasculated government just roll
    over at every opportunity, and follow like sheep. Do you actually know
    anything of the British Empire's history ? It was not about bending people's
    political will. It was about having a world united in friendship and trade.
    Admittedly, it was about ensuring that the trade was to our global
    advantage, but overall, the world was a better and more peaceful place back
    in those days. Now, we have 'superpowers' like the US, who want every
    country in the world to become another US state, with the same language,
    political views, religion, consumer and oil driven economies and so on. And
    you accuse US of trying to bend wills ? Sheesh.

  5. Not only that, but it is pure metallic form Mercury, not some dangerous
    compound(s).

    A very small amount.... In the big, long tubes. An even smaller
    amount in a desktop CFL.

    You said "whenever", Dimbulb. As always, you're AlwaysWrong.
    If "it", no matter what the energy of the electron? Dimmie, you're
    a prize!
    ALL? No matter what the energy of the electrons?
    Dimbulb, you need to look in a mirror, if you can find one that
    won't shatter!

    Brings to mind the old saying: The solution to pollution is dilution.
    Thus, we now have oceanic dead zones off the coasts.

    You assume correctly. However, it is a serious point, because there is more
    mercury in there than the official maximum limit for disposal in regular
    household garbage in Europe (apparently). At my local dump, there is a
    special bin for 'regular' fluorescent tubes, but no mention of CFLs, which
    I'm sure that many people don't realise, also employ the same basic
    technology. Incidentally, in an effort to promote these hateful lights, my
    local supermarket is 'giving them away' for 1 penny each. Another one was
    giving them free with a certain amount of shopping a few weeks ago. So I
    wonder how that equates with the proposals to 'build in' the cost of
    disposal of electronic waste, to the retail price ...?

    ** Just like YOU have loosely bound thoughts.

    Loose a a goose.


    ** Same Wiki page you cited - fuckwit.


    ** The onus of proof is on you to provide evidence - fuckwit.

    Shame you have no idea what that is.


    ** You do have one simple brain.

    Simply fucked.

    Piss off, nut case.

    "Jeff Liebermann Rabid Fucking NUTTER "

    Here:
    http://en.wikipedia.org/wiki/Cathode_ray_tube#Ionizing_radiation

    The first line says it.

    " CRTs can emit a small amount of X-ray radiation as a result of the
    electron beam's bombardment of the shadow mask/aperture grille and
    phosphors. "

    Also, monochrome CRTs ( which have no shadow mask ) emit x-rays as a result
    of phosphor bombardment. Becomes significant with accelerating voltages
    above 20KV, just as with colour TVs.

    Game over - pal.


    Listen up - YOU are nothing but another PITA

    STEAMING GREAT BULLSHIT ARTIST !!!

    SO GO DROP DEAD !!

    Apparently, a VERY HOT iron would:
    http://www.bmed.mcgill.ca/REKLAB/manual/MSDS/MaterialsList/Multicore_370_solder.pdf
    "...BOILING RANGE
    Flux chars above 250°C. The vapor pressure of lead may be significant
    above 500°C."

    Cheers!

    Which is, in turn, about the same level of threat to the environment, as
    lead in solder ... d;~}

  17. Invalid link.

    Long before "flux chars" (and no, not all fluxes would be the same),
    it would liquefy (change phase) and volatize (evaporate in our
    atmosphere).

    Other fluxes would behave differently as well.

    The vapor pressure of a vat of lead at 500 C would certainly have a
    specific vapor pressure.

    Are you sure that the Lead / Tin alloy that solder is would have the
    same vapor pressure?

    Also, there are no irons for the electronics industry I am aware of
    that operate at 932F.

    The search engine string "lead toxicology" should help find the rest
    if the interesting information.
