RE: underwater survey meters

["Lavera, Ron" <Ron.Lavera@nypa.gov>]

We've used the MGP Amp-100.  It has the advantage of being able to be
plugged into the Remote Telemetry Monitoring system, just like the Eds.   It
is a GM instrument with Dead Time correction, so it is linear to within 10%
up to 1000 R/h ( as tested in our shop ).  Calibration is relatively easy.
Instrument cost is reasonable ( for Nuclear Power Plant Applications ).  The
detector housing is about the same size as a Teletector detector head
assembly.

Good Luck.

		we have used electronic dosimeters:  MG or SAIC PDE-4 with
transmitters
		in a plastic underwater camera case.

		the advantage is that you know how your EDs respond vice
your TLDs.

		also, no need to have a separate instrument with parts,
calibration
		procedures, technician qualifactions, etc.

		attach an underwater antenna to the umbilical cord, monitor
with a
		laptop computer.

		personnally, I prefer the PDE-4 for this application because
the exernal
		detectors can be placed on the sides, while the maine unit
is on the
		bottom.  gives directional information.
