Abstract

BACKGROUND: The aim of the study was to present the modified method for the assessment of exposure to electromagnetic field (EMF) in the case of work on a tower or a mast of a large radio television station. The assessment results are included in Reports on EMF intensity measurements, issued for occupational health and safety needs. MATERIAL AND METHODS: Particular emphasis is placed on measurements on radio and television towers and masts where EMF intensity is very high. Since workplaces on towers and masts are not permanent it is not possible to define regular routes or typical tasks of a worker. Therefore, a new approach to the problem is offered. The presented method involves the calculation of maximum admissible dwell time on specified levels of the mast, taking account of EMF dose received by the worker while climbing particular parts of the mast. RESULTS: The results of calculations of the maximum admissible dwell time relative to the level of the specified platform of the mast are presented in Tab. 1 and Fig. 1. The dose received by the worker while climbing the mast reduces (in the given case) the maximum admissible dwell time on the highest platform by about 25%. CONCLUSION: The way the results of EMF intensity measurements are presented in the report allows the worker to plan his work on the mast so that the maximum permissible EMF dose is not exceeded during his work shift.
