Gammacell model 200

[mwilliam@mailbox.uq.oz.au (Michael Williamson)]

Anyone who's institution has a Gammacell 200 irradiator will probably know
by now that the type B(U) transport certification expires on 30 April 1995
and will not be renewed by the manufacturer.  This means that transport of
a 200 for disposal after this date can only be done with a "special
arrangement" certificate  - issued by the competent authority and possibly
costing serious money ($10k to $15k is one estimate) just for the
certificate alone!

Has anyone else been through the process of weighing up the pros and cons
of disposing of a useable piece of equipment now (while the certificate is
still current) or getting a few more years out of it and paying for special
arrangements - assuming that the Canadian authorities will be prepared to
keep issuing such certificates?
