Any threat to health? Garmin Radar Varia

    Hi guys,

    considering buying Garmin Radar Varia RTL 510 bundle.

    There are many reviews and opinions  around since first generation of the radar system from Garmin.  Without doubt, this is a great addition to safety.

    However one aspect that is not covered or discussed is a potential influence on health after long term exposure of cyclist “sitting” on the radar beam.

    Spec: Radio frequency/protocol: 24 GHz @ 12 dBm nominal/2.4 GHz @ 4 dBm nominal

    I believe no one took this particular radar for any scientific test therefore concerns are more of general nature of being exposed to extra  radiation from radar 3-4 hrs a day.

    Any thoughts?

    Update 22.04.2019

    Finally received Garmin Varia RTL510. 

    On rear side of the box there is Warning from California Prop 65 saying “Cancer and Reproductive Harm”. Right way to legally protect itself from Garmin. 

    In supplied doccumentation there is a following text relevant to this post.

    Radio Frequency Radiation Exposure

    This device is a portable transmitter and receiver that uses an internal antenna to send and receive low level of radio frequency (RF) energy for data communications. The device emits RF energy below the published limits when operating in its maximum output power mode and when used with Garmin authorized accessories. To comply with RF exposure compliance requirements, the device should be installed and operated with a mimum 5 cm (2 in.) distance between the device and your body. The device should not be used in other configurations. This device must not be co-located or operated in conjunction with any other transmitter or antenna.

    please calm down, pretty familiar with electromagnetic spectrum and its wavelenght/energy conversion. 

    First of all, Excuse moi my bad English, I interpreted sunbed in a very different way 🙂 

     

    Here in the UK, that’s more like a rainbed.

    This is what I thought of when you mentioned sunbed:

    I think you have described a “single blind” protocol. To be “double blind” neither the subject nor the operator must know whether placebo or real stimulus is happening. The truth should only be revealed at all after all data is collected, processed and analysed.

    Yep, that sounds better – you’d probably have to have the switch operator just record when the electricity is flowing and have several subjects (not in the same room at the same time) reporting symptoms every minute or so (depending on how fast the symptoms manifest) and then have someone else perform the analysis. Maybe wrap the whole testing facility in aluminium foil too.

    @Mungecrundle,

    @Mungecrundle,

    thank you for publishing the link!

    Very interesting. Indeed, there were many studies performed, so questions arose in scientific community accross different fields a long time ago, and  it seems, many were answered. Good to know.

    5G mobile phones also use

    5G mobile phones also use 24GHz, it’s nothing unusual or to be concerned about. I’m a comms engineer, so well versed in polar plots! The dB scale is logarithmic, so a 15dB drop represents a reduction in signal power of nearly 97%.

    And that right there shows you know far to little about the basics of the electromagnetic spectrum to be reading papers on it. 

     

    The sunbed bed has everything to do with it. Both the sunbed and the radar release electromagnetic radiation. The difference being that UV wavelength is much shorter and more dangerous. If you want to worry about electromagnetic radiation being a danger cycling you need to worry about the big yellow fusion reactor in the sky emitting far stronger, more dangerous radiation than some battery powered radar thing.

     

    If you really not convinced I have a radar protection amulet I can sell you for a barren price, and a bag of majic seeds.

    Either WiFi was invented much earlier than I thought it was, or I’ve misunderstood evolution.

    @ Drinfinity

    there is nothing wrong to discuss device made mainly for road cyclists on this site. 

    I am not spamming or supporting any conspiracy theory about pure WiFi signal effect (from which our bodies developped a natural protection by evolution). Thread is related to radar beam.

    Will I do good thing to my frined cycling behind me 5 hours exposing his head to the beam or better I do a favour and cycle in the back? And, what if there are 5 of us with Varia? This is a question.  

    Your sunbed has nothing to do with road cycling neither with electronic devices, it’s  passive; but you are right, if you want to find similar physical effect elsewhere, you always can 🙂

    I do not suffer from any kind of paranoia, including one related to electromagnetical polution and I am perfectly fine in place where I am.  Take care of your health in 1st place and happy cycling ! 🙂

    @Vovis – there’s a place for

    @Vovis – there’s a place for people like you: https://www.bbc.co.uk/news/world-us-canada-14887428

    I don’t mean that to sound rude as I’m actually quite intrigued by conspiracy theories and how they highlight the way that a lot of people think (i.e. tribal thinking and not really understanding why/how the scientific process should work).

    What is interesting is the testing that they did on someone presenting EHS symptoms:

    She was seated on a wooden chair while voltage was applied to metal plates for pulses of 90 seconds to create a series of magnetic fields. The woman was asked to describe her symptoms after each exposure and after random sham exposures when, unknown to her, there was no voltage.

    She reported headaches, pain and muscle twitching during the genuine exposures and no symptoms for the majority of the sham exposures.

    The scientists concluded that such consistency could not be attributed to chance.

    There’s other stories of people reporting symptoms from phone masts when it turns out that the masts weren’t switched on yet, so there’s obviously some kind of hysteria going on too.

    My advice to anyone suffering from EHS is to do some double-blind testing – get someone else to operate the power switch randomly and record symptoms periodically and see if there’s any correlation.

    How one would get certified ionizing radioactive device for consumer electronic sector??

     

    Sunbeds are an example of just such a device.

     

    UV radiation I take very seriously, as it is a very significant health risk that cycling increases my exposure to. Opposite end of the spectrum to radio.

    * I did Skyride Manchester

    * I did Skyride Manchester once with the family. Great event, but I almost got taken out by a cycling smoker who suddenly stopped in the middle of Deansgate to light up.
