[ RadSafe ] Short Half Life = Pornography? or: Relativity ConfusesMe.

Actually the LISTOWNER previously approved  the advertising of certain items 
under certain circumstances, as I most certainly observe.

Mr. Sinebrychoff (KOFF),

I hope to please you with a response - actually nobody seems to response to
your funny messages on RADSAFE anymore....

You obviously try to use the word "pornography" to focus attention to your
ridiculous messages - like the yellow press needs. Sorry, it is new for me,
that radiation protection needs words like "pornography" or probably in the
future pictures of naked technicians (male or female). Since you recently
advertised your collection of outdated, second, third or fourth handed
equipment on RADSAFE (which is actually banned!) I would recommend you that
you withdraw from this list.

You still do not understand, that you are not welcome at RADSAFE?

Colleagues:

I have a question that I'm sure one of you can answer.  It is:  what is
considered a 'short-lived' radionuclide? "

A:
http://hps.org/publicinformation/ate/q5559.html

The NRC GLOSSARY defines half life as:
Half-life The time in which one half of the atoms of a particular
radioactive substance disintegrate into another nuclear form. Measured
half-lives vary from millionths of a second to billions of years. Also
called physical or radiological half-life.


Neither the NRC glossary or the Nucleonics Dictionary define "short",
however 10CFR 61.55 is attempting to classify waste as short or long and
some attempt is being made to improve those definitions, at least by listing
them in a table.







Webster defines "short " as: 1 a: having little length b: not tall or high :
low2 a: not extended in time : brief <a short vacation>

According to this definition, all vacations are short and all lectures are
long.

Everyone seems to know what the "short half" is, especially when referring
to turkey wishbones.



In http://www.nrc.gov/reading-rm/doc-collections/nuregs/brochures/br0216/

radioiodine 131 (8 days) is called a short half lived nuclide, while Pu-241
at 6800 years is called "long".



Yet here is an NRC document referring to Am-241 (432 years) and Np-232 ( 2
million years) both as short:

The US Supreme Court says that they don't know what pornography is, but they
know it when they see it. Short half life seems to be similar to
pornography.



I am 5 foot six. To myself  I am neither short or tall. To my wife who is 5
foot 2, I am tall. To my son who is 6 foot 2, I am short.

In the Masai tribe of Kenya, I am short and come up to their belly buttons.
In Ireland where I am from, I could be a basket ball player. Girls in the
Netherlands are quite tall, and I am about beast high to them. Many Irishmen
like to visit the Netherlands. Perhaps there is a connection.



Go figure
