EMF and its health effects is one of modern topics. Not only RTE intentional equipment but also ITE unintentional equipment is requesting the exposure assessment. For high frequency band, we can declare that comply with ICNIRP basic restriction, as RF emitting power is less than 20mW. EN50371 was published and acting in Europe. Similar standard is now proposed as New Work Item Proposal in IEC TC106. Assessment protocol for emitting power for unintentional equipment such as ITE is not fixed yet. This paper reports our study and finding on this topic.
Measurement around the ITE is not easy way. One approach is estimating the emitting power based on the field strength data or limit value in far field in the meaning of EMI requirement. This first approach was rejected after our study, because of type of anntena and its size in unintentional equipment is unknown. Then far filed strength both electric field and magnetic field was estimated based on the EMI requirement, and find these field strength is very low, such as 1% of reference level of ICNIRP. This second approach is useful protocol for manufacturer of ITE. |
