Subject: TWO LABORERS RECEIVED INTERNAL UPTAKES OF RADIOACTIVE MATERIAL  
                                                                         
Reportable Event Number: N/A

Discussion:

On March 6, 1995, at about 10:45 a.m. (CST), two laborers received       
internal uptakes of radioactive material. The laborers had been working  
in the radioactive waste building loading dried mop heads into a         
radioactive waste storage liner. The area that the laborers were working 
in was posted as a high radiation area but not as a contamination zone.  
Following the workers exit from the work area, the workers were          
discovered to be contaminated. They were externally decontaminated and   
whole body counted. Uptakes of 1491 nanocuries and 381 nanocuries of     
activation and fission products were identified. Twenty hours later,     
whole body counts were again performed and the uptakes had fallen to 270 
nanocuries and 70 nanocuries respectively as a result of biological      
elimination. Dose estimates, as a result of the uptakes, were 116 mrem   
and 30 mrem respectively. Following the incident, smears, taken in the   
area, indicated 30 mrem/hr smearable on the floor beneath the mop head   
drying racks and 100,000 cpm smearable around the top of the liner. No   
other elevated contamination levels were found. The 30 mrem/hr smear was 
analyzed and indicated the presence of both activation and fission       
products. The licensee had not determine where the mops heads had been   
used. The licensee is currently investigating this incident. Resident and
regional inspectors are following licensee actions.                      

Regional Action:

Resident and regional inspectors along with regional management will     
monitor the licensee's investigation and corrective actions. A region    
based specialist will be onsite the week of 03/13/95 to review this      
event.
