Popis:	A system used to transmit data by radio from remote locations within a workplace to a personal computer for immediate interpretation has been developed. The system consists of several radio transmitters and a base receiver that is capable of multichannel reception. Exposure data obtained from any direct-reading instrument with an analog output signal can be displayed and stored at the computer. The worker being monitored carries the instrument in a backpack, along with a radio transmitter. Using telemetry, the concentration of the airborne contaminant under study can then be displayed on a video monitor for immediate assessment while being stored for later analysis. If there is more than one worker under study at a time, multiple exposure records can be displayed on the screen. The base receiver is a commercial (frequency) scanner that has been modified to accept RS-232 serial communication. The manual keypad has been removed so that channel selection is accomplished through system software. In t...
