General Information
1.1 Product Description
The PRIMA® 7 is a general-purpose survey meter designed for the measurement of gamma radiation. It
can be used to determine *TRANSPORT INDEX of packages containing gamma emitting radioactive
material. The telescoping rod, when fully extended, places the detector of the PRIMA 7 at a distance of
one meter from the package being monitored. This is the distance at which the TRANSPORT INDEX is
measured.
Some early models of the PRIMA 7 have a telescoping measuring rod that is three feet long. On these
models, the rod, when fully depressed, protrudes from the top of the case about ¼ inch. On models with
a one-meter rod, the rod, when fully depressed, will protrude about ¾ inch.
