The Model 4590 contains 3.3 MBq (90 µCi) of Cesium-137
(Cs-137) in the form of a sealed source. The source is located in
an extendable source rod. The source rod provides protection
against release of radioactivity under normal use and likely
accident conditions, including fire.
The radiation levels near the Model 4590 are very low.
Therefore, no special radiological precautions are necessary for
operation of the device:
♦ Radiation safety training is not required to operate the
gauge.
♦ Personnel radiation monitoring is not required.
♦ Sealed source leak testing is not required.
♦ Radiation area posting is not required.
The maximum radiation levels in or near the Model 4590 are
shown in the table below:

WARNING!
Do not attempt to disassemble or remove the
radioactive source from this device.
