Beta probes will be placed in plastic begs before issue, 3.1.2 Sfter-Use Instrument Cheek ST. LOUIS FRC 4fter a portable instrumont has been in the field, it will be ruturned to the instrument pool by the using monitor, At this time the instrument will be decontaminated, if necessary, end checked for proper operation and calibration, The instruments will then be stored under proper conditions so as to be ready for re-issue.
