' The results of a hot particle incident'.. investigation was reviewed as noted in the previous Inspection' Report (50-461/89037).: On August 29,

'

1989, a hot particle was found on the-forearm of a radiation protection-technician (RPT) who-had been performing routine work'in the radiological ocontrol area.

The RPT's dose was originally calculated to'be 10 rem to

- the skin of. the extremity.

On January -5,1990, the licensee reported '

-an extremity skin dose to~the individual of 3.8 rem based on"exoelectron dosimetry.
