Subject: MALFUNCTION OF J.L. SHEPHERD, MARK I IRRADIATOR

Discussion:

On April 23, 1999, the RSO for NIH informed Region I, Division of Nuclear
Materials Safety, by telephone, that its J. L. Shepherd, Mark I
irradiator had malfunctioned.  NIH's license requires that they
immediately stop use of the irradiator and notify the Commission by
telephone if abnormal levels of radiation or any malfunction of the
irradiator is detected.  On April 21, 1999, NIH detected that the source
had not fully retracted to the shielded position.  The RSO indicated that
there were no elevated radiation levels adjacent to the irradiator.  NIH
has taken the irradiator out of service and has contacted J. L. Shepherd
for service.

Regional Action:
