We’re fielding a lot of questions about which personal monitors should be used for 5G. Just like any other EMF safety application the question is what frequency range do you want to cover?
And here lies the confusion about 5G. There are various 5G frequency band allocations all the way from 700 MHz to 86 GHz. The important point to note is that general network roll out will centre on the lower frequency bands e.g. 700 MHz & 3.5 GHz plus maybe the 26 GHz band and the 60 GHz & 80 GHz frequencies will be used for specific applications. From an EMF safety viewpoint field strengths will be limited at the high frequencies simply because it’s difficult and expensive to generate high power levels at these frequencies.
So to choose a personal monitor it’s not really sufficient to talk about 5G in general terms. You need to identify what 5G bands your personnel will be working with. If it’s 3.5 GHz then it’s an easy relatively low cost solution (Radman 2 LT 50 MHz to 8 GHz). If it’s 26 GHz then it’s still a straightforward solution (Radman 2 XT 900 kHz to 60 GHz), just more expense. If it’s >60 GHz then it’s a more complicated solution where we would look at bespoke calibration of the Nardalert S3. Standard Nardalert S3s are specified to 50 GHz so are suitable for use with 5G frequencies <50 GHz (as is the Nardalert XT) but the thermocouple sensor used in the Nardalert means 100 GHz is potentially achievable.
ICNIRP (International Commission on Non-Ionizing Radiation Protection) have released their new radio frequency guidelines (100 kHz to 300 GHz) in draft form for comment.
EMF safety is a niche subject and those involved with it on a regular basis often take things for granted and use terminology that is far from easy to understand. Plus with the EMF Directive & CEMFAW Regulations in place it's made it necessary for more health & safety professionals and engineers to grapple with the subject. The Narda Safety Test Solutions booklet 'Everything you wanted to know about safety in electric, magnetic & electromagnetic fields' is a great place to start or provide some more background knowledge for those that already know a little about the subject. Just click here to download a great free resource that explains the EMF safety basics and more.
We've added additional dates for EMF safety measurement training. The courses will be held at Link Microtek in Basingstoke.
We're pleased to have been invited by IOSH to present another EMF safey webinar. The last was an overview of the EMF Directive & the CEMFAW Regulations.
Anyone interested in a quick overview on the Control of Electromagentic Fields Regulations 2016 / EMF Directive 2013/35/EU can view a recording of the recent IOSH webinar by clicking here.
On behalf of IOSH (Institute of Safety & Health) we recently presented a webinar on the Control of EMF at Work (CEMFAW)Regulations 2016.
The Control of Electromagnetic Fields at Work Regulations 2016 (CEMFAW 2016) are essentially the requirements of the EMFDirective 2013/35/EU transposed into UK law.
OK, first up, exemptions and derogations are the same thing. EMF Directive 2013/35/EU just uses the term derogations whilst in the UK, HSE in the CEMFAW regulations have decided to use the term exemptions.
So the implementation date for EMF Directive 2013/35/EU of 1st July 2016 passed and the world kept turning.
The use of EMF safety area monitors makes sense in many environmental applications e.g. if a community has concerns about ambient fields and wants to monitor levels over a long period of time then area monitors are a useful tool.
Alas the murky world of EMF safety measurement equipment isn’t straightforward and we're seeing equipment coming to the market that is less than adequate.
