What is a PBq? -Reply

[William MCCABE <MCCAWJ@doe-md.gov>]

The "P" stands for the prefix peta which is ten to the fifteenth power. 
See http://www.umich.edu/~radinfo/ for other useful SI prefixes.

Can someone out there tell me what the 'P' in PBq stands for? See it in
context below:

Department of the Army (also known as TACOM-ACALA, Army, and
Licensee) is
the holder of NRC License Nos. 12-00722-06, 12-00722-13, and
12-00722-14
issued by the Nuclear Regulatory Commission (NRC or Commission)
pursuant to
10 CFR Part 30. The licenses authorize possession of up to 1.5 million
curies (55.5 PBq) of tritium, 25 curies (0.93 TBq) of americium-241, and
1000 curies (37 TBq) of nickel-63 for use in self-luminous fire control
devices, in chemical agent detectors, and in chemical agent monitors.
The
licenses authorize use and storage of these devices at Army, Marine,
and
Navy installations throughout the United States. The licenses were
initially
issued on June 23, 1977, May 23, 1984, and May 3, 1985, respectively,
and
each is currently due for renewal or in the renewal process.
