I personally experienced the next: 1) radiation level depends on flight altitude, just in case check flightradar24 data for your flight to see if they moved higher when you saw an increase of readings 2) radiation level depends on latitude, more to the north - higher the radiation level and vice versa 3) gamma spectrum shows a peak near 511 keV, evidence of positron-electron annihilation 4) muons are detected directly by both scintillators and geiger counters, and register rate is close to 100%, as far as I remember. But conversion rate counts/sieverts is different and, probably, wrong for both detectors. 5) there is a very rare case which is called “gamma glow” and could happen during thunderstorm. I’d be happy to detect it as well
Also, I suspect the FS 5000 is calibrated with cesium 137, and I know the radiacode 102 has a compensated calibration for energy and temperature, so it would give you an accurate dose while a geiger counter won't unless it's cesium 137 (or whatever it's calibrated with since older units may or may not be to the standard of modern detectors)
@@The-One-and-Only100 radiacode should give kind of accurate measurement in its own range, i.e. below 3 MeV. However, there are a lot of particles with higher energy.
The issue is that a lot of the CR collision debris is not giving much of a gamma release in the low energy levels that the RC102 can detect (typical energies will be many orders of magnitude above the 3MeV limitation), there is quite a lot of beta and even alpha and some weird short lived bits-n-pieces. When a single proton can have an energy level that gets up to the mJ level (the OMG detection event recorded 50J, imagine that hitting something squishy between your ears), then anything it hits is going to have a really bad day.
🙂 As usual, I enjoy your little videos and find them interesting. I need to transit through USA with AA at least couple times a year... Last spring, my transcontinental flight was "Premium economy" ... for the short AA flight before this, I was bumped up to business since there's no premium economy on that short flight. The business flight attendant's name was Shirley. I was so tempted to quote Airplane and say “Surely you can't be serious"... If I see her again, I definitely will. Maybe my little anecdote will be enjoyable. Some day, I may get my shit together enough to make interesting little videos.
be careful making jokes, on both the outward and return flights, the AA crew were a pretty miserable bunch. I hate for her to decide it was time to summon the air marshal...
I did exactly this on a long trip in the air. I measured audio intensity and radiation with a cheap Geiger . What surprised me was how loud a plane is at lower frequencies. If I recall it was well and truly above safe levels for hearing lose . You might measure this next time and see what you think.
I have done that before, I have some pretty advanced sound recording equipment (one of my day-jobs is acoustic R&D), it sort of approximates double brown noise with harmonics from the engine... As you say, the LF components are really unacceptable, particularly towards the back of the bus, IE behind the engines.
That was very well done! I really like your videos! Ionizing radiation is my go-to hobby! That's a real shame about the imDetek RAM-01-which uses CZT, yet it's a PoS! That sucks! I'd love to get a gamma ray spectrometer that uses CZT! I really hope Radiacode or Raysid will consider improvising their devices with CZT, for example! It has much better resolution-comparable to CeBr3! Now, I don't own one, but I'd like to get one someday. I have a GammaSpectacular GS-PRO with the 1.5" NaI:Tl crystal-which interfaces with my small laptop. I'd prefer one a larger crystal, like 3", but it was pricy. Thank you for sharing your findings and work!
nice measurement, did you try over Kerala India or Minas Brazil? The background there is about 80 times higher then average. Maybe you may try the CZT at high exposure, it is known for the low sensitivity and high spectral resolution. There is the other Geiger counter type based on photodiode and is as low sensitive as about 10 cpm/ uSv/h, but should also mean the low background for alpha and beta count. Some studies refer to higher disease incidence at the crew, related to higher radiation exposure.
Another very interesting and very well made video sir! There is also quite a bit of neutrons up there! You`re right about the Cd/Te (Zn) detector, their are very good generating spectrum! My X-ray spectrometers allows for XRF identification and has a small Cd/Te detector. Ultimately, the size of the detector determines the max energy (roughly speaking) They really missed the mark on that one for sure! give it time maybe they`ll come up with upgrades?
Clearly there is a fairly serious design issue, probably in the electronics (assuming the sensor itself is fine). But what is encouraging is that a $50 device can have a CZT detector, and this bodes well for the future...
TSA doesn't think the radiacode 102 is for insulin... darn, I guess I can't get on the plane faster (Do they question you why you have one or three, I haven't gone through TSA in years)
If you had $300-$400 to spend on a detector which one would you pick. I was eyeballing the 103. I have started working on radium clocks and I was wanting something sensitive enough to check my work area for contamination. Thank you
for sure, get the RC103, or if you can get it, the RC103G (I'm going to be reviewing that one soon). Be VERY careful with radium dials. The phosphor breaks down in just a few decades (so doesn't illuminate any more) but the radium has a half life of 1600 years, so is still just as active as when it was made. If you see any dust, don't open it...
@@project-326 that’s why I’m concerned and wanted a sensitive detector as I bought a bunch of clocks in a lot and one has a bunch of dust from the radium on the inside of the glass. It got bagged immediately and I wanted to scan the area. My fs5000 is not nearly sensitive enough to find any contamination.
@@jtcustomknives use a UV flash light to find all of the dust, it might no longer illuminate from the radium but a dose of UV will make it fluoresce, and hence easy to find.
An old friend from university used to work for Boeing (15 years, mostly on 777 avionics) and he told me that he would never fly on a 727 Max - this was a couple of years before this model became infamous...
Do you have an opinion on the GQ GMC -500Plus? I am trying to stay below $200 usd, but I can't tell if any in that pricepoint are worth it, or if I should just wait and spend more.
Sorry but I have never personally tested the GMC devices. I hear that they are of reasonable quality, but also hear complaints too. Most of the GMC range uses the J321 tube, which is a reasonable choice for a mid-range device but the response time of their firmware averaging is very slow according to many of the comments I have read.
Good data. Try and repeat in 5 to 7 years during the next solar minimum. The background should increase due to less solar wind pushing cosmic rays away.
Because of the solar max next year, I am actually considering getting a reasonable solar telescope. Very interesting information about the solar wind effects, is this due to cosmic ray deflection occurring at the termination shock region?
@@project-326 AFAIK yes. The increased density of solar wind pushes the termination shock farther away at the solar cycle maximum, causing more of the particles to miss inner Solar System.
Nice! I like the transitions and effects and animations you include and they're getting ever more professional! I may get one of them bosean devices. So I could also partecipate in your gm tube experiment.. I'd have wished to see the "the other of the Chinese devices you tested and I'm fighting with too" up there! Or is it too risky to loose it to some ignorant uniformed twit?
I'd be curious to see you do a review of the "Terra-P" (by Ecotest)... It's what they use at Chernobyl, so I'd assume they did their due diligence, but you never know haha
It seems like a 'reasonable' beta and gamma detector, but it is just way too expensive for me to buy and review. The SM-20 tube is good, but the device features are like a 30 year old product...
I've been driving around here in NorthEast Ohio, USA with my Radicode 103. I have to say it's pretty boring here radiologically speaking. My basement where I sit is only .05 micro-Sieverts per hour. The only thing that gives it a boner are my samples of different elements. Cool viddy!
Most of our atmosphere is below 15km. Planes fly at 10~12km. I don't care. That tiny bit of radiation is for most people the last thing they should worry about.
I completely agree with you, long haul flights give total exposure levels that are around that of a dental x-ray. What is exciting about it is that gives the opportunity to directly measure secondary cosmic rays, before the atmosphere absorbs most of the debris...
yes, it is exactly like that and it is the part of the plane where the attendants forget how to smile. All airlines claim they treat passengers with TLC. Thing is, AA treats theirs with TDC (thinly disguised contempt)...
I appreciate your humor.
You're a real ray of sunshine.

very interesting video once again, i hope for a bit more cursing next time :D btw, i think i'm going to order an FS-5000 as a first detector
Maybe the telluride sensor responds strictly to gamma only, so it ignores muons. I think it's worth testing with a stronger gamma source.
Actually I have done - its still terrible. But thanks for the thoughts!
