• Description:
  The purpose of this study was to determine whether electromagnetic interference caused by operation of hand held radio transceivers effects the readings obtained by commercially available audio dosimeters. Sixteen dosimeters, used in routine monitoring service for at least 2 years, were studied and two hand held radios that had been in use more than 1 year were used to generate the radio frequency field. Exposures were conducted in a reverberant chamber at levels of 36, 80, and 92 decibels-A to an octave of noise centered at 1 kilohertz. During the recording period, the radios were operated on two duty cycles, 2 or 3 cycles/minute. For each noise, exposure condition reported measures were compared with and without operation of the radios. Each of the dosimeters tested was susceptible to radiofrequency waves within 1 foot of the radios transmitting at the frequencies studied. The dosimeters worn in close proximity to any radiofrequency generating device will record the exposure, thus giving falsely elevated readings. The authors recommend measures to identify possible radiofrequency contamination on dosimeter performance in the field. [Description provided by NIOSH]
