20555 Gentlemen:
~.
We are reviewing our emergency procedures in regard to radioactive mauerials, and have some questions about the possible effect of a fire on a five-curie (80-gram) plutonium-beryllium neutron rource.
I note that the ANSI standard adopted in 1977 specifies that such a source will tolerate 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> at 400 C.
However, our source was shipped in 1963 by Nuclear Materials and Equipment (IRTMEC) of Apollo, Pa.
It bears the serial number 800-P-8.
Co.
A catalog in our files, dated 1962, describes a ecdel NUMEC-P encapsulated in a container whose side walls consist of.03 inch stainless steel lined with.07 inch tantalum.
.The ends are
\\
s heavier.
Since I an unable to find a current address for MUMEC, I
wonder if you have in your files a record of the safety criteria under which this product was originally licensed.
If so, I would be grateful for information regarding those criteria.
Incidentally, our own license for this source is number SNM-554.
I regret the necessity of adding to your workload at this hectic ti;:te, and will be grateful for any help you can give me.
Sincerely, V
MW Baruch S. Jakobson Physics Department Radiation Safety Officer Brooks Hall
