In NRC Reg. Guide 8.25 section 3.1, entitled "Need to Demonstrate that Air
Sampling is Representative of Breathing Zone Air",  item (4) states "results
from lapel samplers or samplers that are located within 1 foot of the worker's
head may be accepted as representative without further demonstration.."
