     The question is a very good one. Based on 10CFR20 and pertinent State 
     Regulations, the requirement for badging an occupationally exposed 
     worker is that they are expected to exceed 500 mrem in a year. Very 
     few dental technicians should exceed this value for most are shielded 
     behind a wall when they operate the x-ray equipment. 
     
     The basis for wearing a dosimeter is therefore based on several 
     factors. These are:
     
     1. Worker concern
     2. Litigation concern on the dentist's part
     3. Volume of work and how close the technicians approach the           
        regulatory limit
     
     The pregnant worker has a different limit to be concerned with. The 
     NCRP recommendation for the fetus is <500 mrem during the gestation 
     period. Again, the probability of a majority of dental technicians to 
     approach this dose is small.
     
     Another approach to consider is to place several film badges or TLD 
     dosimeters around the area where the technicians work and use those to 
     assess whether or not individuals need to be monitored or not. These 
     dosimeter results should also be maintained as a record to document 
     what types of exposures technicians may have been exposed to.
     
     If dosimeters are worn by the technicians, 10CFR20 and State 
     Regulations require that the individual be informed of their exposure 
     on an annual basis, and, whenever they request it in writing. The 
     information is also required to be sent to the NRC on an annual basis, 
     or, to the State as appropriate.

Since the office is a dental office is it necessary to badge the individuals 
or office?   It may only be necessary to monitor pregnant employees. 
Check the NRC or State Regulations first.
