Fast Neutron Irradiation

Arabidopsis Folk-
	As you know, Fast Neutron irradiation has been a popular mutagen
due to the prevalence of deletions and genomic rearrangements found in
mutant alleles from this treatment.  I have received word from the IAEA
(below) that they will no longer be able to provide this treatment.  I am
concerned about the future prospects of using Fast Neutron irradiation as
a mutagen.  Does any one know of alternative providers of this service, or
if not what can be done to prevent the loss of this asset?

Dear Dr. Metz,

We regret having to inform you that we will no longer be able to provide an
irradiation service with fast neutrons.

For many years, the Plant Breeding Unit of the IAEA Laboratories in
Seibersdorf has provided a cost free service of treating plant material with
fast neutrons. This treatment was carried out using the research reactor of
the Austrian Research Center, Seibersdorf. This reactor will be closed down
at the beginning of July 1999 and at that time the service will cease.
Currently we are not able to recommend an alternative institute which could
provide this service, although there are several research reactors
throughout the world which may be in a position to offer such a service.

If you would like to have some more material treated, the last two possible
times of radiation will be in the weeks of 7 - 12 of June and 28 June - 3
July. The radiation service with gamma radiation, which the IAEA
Laboratories currently also supply, will not be effected by these changes.

If you need any assistance in radiation service or have any questions,
please do not hesitate to contact us.

Kind regards
