µECD warnings
Although beta particles at this energy level have little penetrating power —the
surface layer of the skin or a few sheets of paper will stop most of them—they
may be hazardous if the isotope is ingested or inhaled. For this reason the cell
must be handled with care: radioactive leak tests must be performed at the
required intervals, the inlet and outlet fittings must be capped when the
detector is not in use, corrosive chemicals must not be introduced into the
detector, and the effluent from the detector must be vented outside the
laboratory environment.
Warning Materials that may react with the
or to cause physical degradation of the plated film, must be avoided. These
materials include oxidizing compounds, acids, wet halogens, wet nitric acid,
ammonium hydroxide, hydrogen sulfide, PCBs, and carbon monoxide. This list
is not exhaustive but indicates the kinds of compounds that may cause damage
to 63Ni detectors.
Warning In the extremely unlikely event that both the oven and the detector heated zone
should go into thermal runaway (maximum, uncontrolled heating in excess of
400 °C) at the same time, and that the detector remains exposed to this
condition for more than 12 hours, take the following steps:
Released: March 2004
Owners shall not interfere with or attempt to defeat the overheat circuitry
that may be supplied with the µECD.
Owners shall not transfer the µECD to another person or another location
except as described in the applicable Regulations.
Owners must perform a radioactive leak test at least every 6 months or as
required by your local Agency.
Owners must maintain records as required by your local Agency (the NRC
or, in certain states, a state agency).
Owners must notify the Agency in case of incidents or failures that might
lead to a hazardous condition.
