Abstract
A method for monitoring exposure time of workers involves the use of a sensor, which is carried by the workers for monitoring continually in a real-time fashion in an environment such that the results are recorded by a recorder. The an add-on or built-in timer in the sensor or the recorder is used to monitor time, which is recorded in the recorder simultaneously, so as to obtain the real-time continuous exposure level of a hazardous material in the environment.
