Opis:
Objectives Electromagnetic fields (EMF) may cause malfunctions in electronic devices, in particular in active implantable medical devices (AIMD), along with discomfort or health hazards to users. The use of AIMD by workers is increasing (especially cardiac pacemakers, implantable cardioverter defibrillators and wearable insulin infusion pumps). Electromagnetic fields may be much stronger in the working environment than applied in basic immunity tests of AIMD (based on EN 60601- 1-2:2015 and EN 50527-1:2016). European Directive 2013/35/EU regarding the safety of workers exposed to EMF considered the AIMD users to be “workers at particular risk” who need an individual evaluation of EMF hazards. The study aimed at evaluating the safety of users of AIMD in medical and industrial working environments exposed to EMF Material and Methods Near the common sources of strong EMF applied in medical and industrial use, the “standard safety distances” (SSD) for AIMD users were evaluated (i.e., distances from the EMF source, where exposure drops below limits from Recommendation 1999/519/EC and AIMD safety may be expected). The analysis is based on the results of measurements of magnetic and electric field strengths near 127 typical devices, in their normal use. Results The longest electric field related SSD was identified near dielectric sealers (up to 180 cm), and the longest magnetic field related SSD – near induction heaters (up to 450 cm). Conclusions Electromagnetic fields related AIMD malfunctions need to be considered up to several meters from EMF sources. The “individual safety distance,” that is sufficient to ensure the safety of a particular AIMD user may be significantly different (usually shorter) from the presented SSD, but needs to be considered in the context of detailed safety data from the AIMD manufacturer (if available). The labelling indicating the location of the area of a strong EMF increases safety of AIMD users in the work environment. Int J Occup Med Environ Health 2018;31(6):795–808

Opis:
Objectives: The aim of the study was to identify and assess electromagnetic radiofrequency radiation (EMRR) exposure in a workplace located in a publicly accessible environment, and represented by offices (where exposure is caused by various transmitters of local fixed indoor and outdoor wireless communication systems). Material and Methods: The investigations were performed in 45 buildings (in urban and rural areas in various regions of Poland), using frequency-selective electric field strength (E-field) exposimeters sensitive to the EMRR with a frequency range of 88–2500 MHz, split into 12 subbands corresponding to the operating frequencies of typical EMRR sources. The variability of the E-field was analyzed for each frequency range and the total level of exposure by statistical parameters of recorded exposimetric profiles: minimum, maximum, median values and 25–75th – percentiles. Results: The main sources of exposure to EMRR are mobile phone base transceiver stations (BTS) and radio-television transmitters (RTV). The frequency composition in a particular office depends on the building’s location. The E-field recorded in buildings in urban and rural areas from the outdoor BTS did not exceed respectively: medians – 0.19 and 0.05 V/m, 75th percentiles – 0.25 and 0.09 V/m. In buildings equipped with the indoor BTS antennas the E-field did not exceed: medians – 1 V/m, 75th percentiles – 1.8 V/m. Whereas in urban and rural areas, the median and 75th percentile values of the E-field recorded in buildings located near the RTV (within 1 km) did not exceed: 1.5 and 3.8 V/m or 0.4 and 0.8 V/m, for radio FM band or for TV bands, respectively. Conclusions: Investigations confirmed the practical applicability of the exposimetric measurements technique for evaluating parameters of worker’s exposure in both frequency- and time-domain. The presented results show EMRR exposure of workers or general public in locations comparable to offices to be well below international limits.
