[SPAM]RE: [ RadSafe ] What Are Radionuclear Materials?

[Doug Aitken]

I think the problem is the use of nuclear, a the nucleus is not always
unstable.....
I like the clear distinction that the use of the "radio" seems to bring.

The use of radionuclear seems to be common in medicine and is clearly
understood to material that emits radiation (used for irradiation therapies)
and not necessarily linked to dispersive events (contamination as in RDD's)

Of course, "nucular" (sic!) is a commonly used term here in the US. I guess
any term used will confuse and therefore scare the general population.....

Thanks Doug for your comments.

I agree with your comment about "nuclear material". The confusion
however arises from the common use of the following terminologies: (1)
improvised nuclear device (IND); (2) radiological dispersal device
(RDD). "Radio" suggests an RDD while "nuclear" suggests an IND.
Radionuclear therefore could be misinterpreted to represent a nuclear
event with radiological dispersion (as actually occurred in Hiroshima
and Nagasaki). In addition, nuclide
(http://www.nucleide.org/DDEP_WG/DDEPdata.htm )relates to isotopes while
nuclear as used here relates to the atomic nucleus (e.g., nuclear
fission [http://www.atomicarchive.com/Fission/Fission1.shtml ]).

I don't see a problem with the term.
Radioactive isotopes are often called radionuclides, so why not
radionuclear
materials? Is seems a self-evident term, certainly more meaningful than
the
common nuclear material, that really does not mean anything....

Doug

Colleagues:

 

The terminology "radionuclear material" appears in some recent
publications that relate to possible future food supply contamination
carried out by terrorist (e.g., WHO 2002; Mohtadi and Murshid 2009).
Can someone define or explain what is meant by radionuclear material?
Isn't this improper terminology?
