Where:
P = Precision
n = Individual measurements
m = Average of measurements
N = Number of measurements
If the actual count rate precision obtained above is divided by the
theoretical precision, a test can be made of the Gauge stability. The resultant
value, R. will indicate electronic noise in the circuits or an unstable detector.
The equation for this test is indicated in 5.5, and the gauge has this function
included in the software.
8 RADIATION SAFETY
The user of this equipment should study the Radiation Safety Manual, which
is supplied with it. If available, a formal course on the subject is desirable.
While the radioactive materials in the Gauge are very small amounts and
only a major accident to the Gauge could cause an immediate hazard, care
should be taken in its use in order to keep exposure as low as reasonably
achievable.
Remember that short time and long distance are the most effective means of
minimizing the user's exposure.
Refer to the Radiation Safety Manual for more complete details of safety
procedures.
8.1 Licensing
Prior to receipt and use of this equipment, the user must obtain a
Radioactive or By product Material License from the government agency
responsible for the purchaser's area.
The licensee must have a Radiation Safety Officer who has received training
in safety and applicable regulations. He will be responsible for the initiation
and maintenance of a safety program for the users. All records and inventory
controls must be available for inspection.
