Worried about 5G?

One manufacturer produced products with elevated actinium/radium levels, and the rest have elevated thorium/uranium levels.

The radiation levels reported are typically in the vicinity of .01 to .02 uS/hr.

The Dutch really do have stringent standards.

I was thinking the issue with air traffic .. which was sufficiently explained.
Anyway .. 0.01 uS/h is hardly detectable. Highest value is 0.13 .. which is still bellow background at the place I sit right now, which is 0.22 when I write this.

Ok, guess I can live without one. This is just too weak.

I hate pieces like this. These are external Beta sources (with some Alpha). There is virtually no penetration into living tissue.

And any radiation readout in Sieverts or uSieverts by an instrument such as shown is in terms of a reference gamma emitter. A Sievert is s J/kg deposited energy for gamma. There is a multiplier for beta or alpha because they have more biological effect.

But all of that presupposes the alpha or beta's source is distributed internally. External sources of alpha and beta barely go through much air let alone into your tissue.

Now along the decay chain there is usually some isotope with a gamma decay. That's the one that actually matters unless you have a fetish for grinding up and consuming the trinkets.

To put this in perspective, I have a Geiger survey counter from 4 decades ago that has a thin membrane and can pick up gamma, alpha, and beta. It's calibrated for gamma.

I also used to buy de-static brushes for 35mm film for about $20 each in a department store. They had Po alpha emitters that were so strong they would peg the meter at the highest scale (200 mrem). Rather than click-click, the Gieger counter would just hiss. They were so radioactive that when I brought them up to a fluorescent poster in a dark room the ink would glow. If they were newly made. Half-life about 100 days. Pretty much useless for anti-static purposes after 2 years.

But I also had no problem putting the anti-static brush in my pocket when going to the photo club. I also understand the physics and biological factors.

As for thorium, I also have an old Aladdin oil lantern that has a mantel coated with thorium oxide. It will noticeably increase background count from a foot away. And click nicely within a few inches. Beta mostly. Very nice lamp.

They (anti 5G trinkets) are scams but are they dangerous? Almost certainly not.
 
The rollout of 5G in the US will be delayed until at least January 19...

... after AT&T and Verizon backed down in a fight over aircraft safety

For those who doubted there were any concerns about 5G and aircraft navigation systems...

https://www.businessinsider.com/5g-rollout-delay-att-verizon-u-turn-faa-pete-buttigieg-2022-1

"Buttigieg and the FAA sent a letter to the two companies on December 31 asking them to delay their planned rollout of new C-band 5G networks by two weeks, citing concerns over disruption to plane safety equipment. The letter said the disruption could have a knock-on effect that would cause flights to be diverted or canceled."​

I hate saying I told you so.... but... I told you so!

I try to avoid anything 5G as YES it is dangerous to our well being....

5G Ultra wideband being the worst.......

Oh, do tell!

What is it specifically that is "dangerous" about radio waves at the frequencies used by 5G especially the "wide band" radio waves?

Why are they "dangerous" when compared with the range of frequencies used by 4G or 3G, navigation aids and beacons, or police, fire, ambulance and aircraft radio transmitters, broadcast radio stations, televisions stations or amateur radio transmitters?

I can't wait to read your answers to these questions.

You do realize that visible light is both more "wideband" and more energetic than the radio frequencies used for 5G, right?

Heck, stack all them there bands together and you've got super ultra extended multiple un-banded transmissions. Why the heck some particular transmission banding should make a difference to the almost infinitely possible un-banded nature of exposure, is beyond me.

As noted, other natural 'bands' of EM radiation are far more dangerous.

AND those same 5g bands have been in use since the 60s for UHF TV.

A question about this chart. It equates high frequency with high energy, and low frequency with low energy. Is that really true? Isn't the energy a function of transmitting power? For example there are lots of AM radio stations transmitting with 50,000 watts. Isn't that pretty high energy?

It is high energy. But individual photons have low energy, and that's what counts when damaging tissue and especially DNA (thus causing cancer).

All EM spectrum does heat up matter, as long as it's not reflected. Microwaves, FM radio, IR from stove, or visible light. And enough heat will damage cells. So microwave will kill your hamster.

But only UV and up there is some chance of damaging cells inside without killing them.

Well that's one way to think of Energy, as Power x Time or you can think of Power as Energy / Time. Since frequency (v) is the inverse of wave cycle time (t), v =(1/t). Wave Power becomes Energy x Frequency. Now the wave Energy per cycle formula is E = hv with h being Planck’s constant. Combine the two and the wave Power to Frequency relation is P = hv2. So while wave Energy is proportional to Frequency, wave Power is proportional to the square of Frequency.

One way to think about it is that in a given time period a higher frequency has more cycles and thus can deliver more energy and more power in that period of time. For a given power, like 50,000 watts a higher frequency can deliver that amount of power in a shorter period of time (T)than a lower frequency. So at 1 and 2 cycles per second P=E/T so E is h x 1 and h x 2 respectively. Solving for T we get T = E/P or 50,000/ (h x 1) and 50,000 / (h x 2). So twice the frequency means half the time to deliver the same amount of power.


ETA: made a mistake in the formula for T from a set P give me a minute.


ETA2: Ok problem was my time in one case the inverse of time per cycle (v) and the other total time I'd have to relate total cycles for each v to get the total Time for each. or use the power per cycle equation from before P = hv2. So power total divided by power per cycle gives number of cycles and number of cycles over cycles per second (v) gives Time total. Ttotal = Ptotal/hv3. Which still doesn't look right, well you get the idea, hopefully.

How is energy related to the wavelength of radiation?

Standing close to a 50,000 W AM transmitter will likely cook you due to the total amount of energy you'll absorb but the individual photons will not have enough energy to break the chemical bonds in your cells which is what causes cancer. AM frequency radiation is non-ionizing regardless of transmitting power.

The transmitting power of 5G phones is in the 10^0 watt range. Put your hand under your desk lamp and you'll absorb far more energy (or at least used to before LEDs :) ). Still just as heat though.

For a time I lived within a quarter mile of a 50,000 watt FM station transmitter. I was using a discman as my entertainment system CD player. If I just held my hand over it it would continuously skip and it only happened there, I used it in my car as well. I also had a pair of touch activated three way lights. Only very late at night they would just start and continuous cycle through the three modes. I eventually had to put mechanical three way switches in them as the light show kept waking me up at like 2 in the morning.
 
So I tried looking for the pendant, with intention of buying it. And I couldn't find it !
Few days back it popped up amongst Facebook ads - on Aliexpress of all places. Which isn't so weird after all. All is made in China, especially woo. Should have searched there first.
Well anyway, I made some research, to be sure to get the radioactive one .. and it seems it's not that hard. There are only few models. And they are being sold for YEARS !
When I knew the exact product name, I tried looking at youtube, as after all these years, radioactivity enthusiasts certainly must have caught up on it. And they surely did !
Here is nice review with best measurements I could found, including gamma spectrometer. Which I was kinda curious about, it's good to know what's in it for storage and handling purposes.

In short it seems to be some natural ore, lots of isotopes, not really too hot, just slightly more than uranium glass. Produces pretty much every possible particle. Probably some uranium mining waste.

There is also one model with similar design, which is clearly uranium glass. Looks like radiation is indeed design feature, not some mistake. On some of the shops they even have photos of the pendant being measured with geigers .. except the geigers are relabeled as 'ion meter'. You can get certificate it has 3000 ions.

So I ordered one straight from China, for $2. Now let's hope the customs won't stop it. Guess it will depend on how the shop will declare it.
