Modelling the risk of electromagnetic field hazards with the use of computer dosimetry

Project manager: Jolanta Karpowicz M.Sc. (Eng.)

Project summary:

As a result of measurements of electromagnetic fields at real workstations, data on the size of the fields, the character of workers' exposure and the organization of workstations were gathered. They were then used to develop numerical models and to verify the results of numerical simulations of electromagnetic hazards. The possibilities and the necessary scope of using computer dosimetry to assess the degree of workers' exposure to electromagnetic fields were analysed.OPERA software was used for numerical assessment of workers' exposure in two most extreme cases of exposure: in low-impedance fields at resistance welders and in high-impedance fields at dielectric welders. To compare the results of the simulations with the use of various computer programs, a simulation of a distribution of an electric field in the vicinity of a dielectric welder was also conducted. The use of numerical simulations in assessing workers' exposure to electromagnetic fields was assessed. The simulations showed that computer dosimetry can be a convenient and efficient method of assessing electromagnetic hazards present in the working environment.
