RE: Short term vs Long term (Atmospheric release)

["Lieskovsky, Miro" <MLieskovsky@nbpower.com>]

Dan:
As per Canadian Standard, CSA 288.2, and if I remember well (I do not have
it here right now):
short term release (10 min to 1 hour)
prolonged term release (1 hour to 24 hours)
and (I assume) long term release > 24 hours.

Generally, the Gaussian dispersion is defined for each term and it reflects
the probability of wind directions and other weather characteristics.

What is the difference between short term and long term release?  How are
they defined? and what published reference can you give that shows these
definitions?

Also, what ultimately dictates whether an atmospheric release is considered
 short term or long term?
