    Is the model number a reference to the radiacode 103g or just a big coincidence?

    • @project-326
      @project-326  2 дні тому

      I think it is coincidence, the Radtus device has been round for longer than the Radiacode devices, and the Radiacode models have just incremented the numbers and now reached 103...
      But the 'G' suffix is also interesting, RC103G represents the GAGG crystal, but again the Radtus used it first. Spooky...
      I saw that the Radtus creator is making comments, perhaps he can help answer this better than me.

      In fact, there is no letter G in the model designation of my device. There is a little confusion here.
      As for the close matches in the model designation with Radiacode, this is exactly a coincidence. And my device with such a designation was much earlier than Radiacode came to the same thing. We just had the same thoughts. Decoding the designation is simple - 1 is the model number, 03 is the revision number. I keep in touch with the Radiacode developers. We have already discussed this with them. :)

      All this costs quite a lot of money (for me at the moment). I simply don't have it. Besides, this device has at least one thing that is suitable for patenting. But again, in order to reliably protect some solution with patents, you need to get at least three patents - US, EU and Japan. All this together costs about 100,000 dollars. For me - it's completely unrealistic. And there is no point in patenting in Russia, since no one in the world recognizes Russian patents.

      @@Radtus-R103 the only place I bother with patents these days is in China (with additional PCT filing), everything is made here anyway and the system here is good to protect IP if you have a local patent with first filing in CN. Even with my foreign name on the 19 or so patents that I have, not seen any infringement in China. Ironically, the only copying that has occurred with any of my IP was from a shitball UK company and an even shittier Canadian company (both of which had been clients of mine). In both cases the Chinese factory they went to get their products made at actually contacted me directly to let me know and stopped the project. A lot has changed in China in the last 10 to 15 years (but most people in the west don't know, or even want to know that). They now have a growing portfolio IP of their own to protect...
      What most people forget is that until WW2, the US was built on IP copied from Europe, after the war, the Japanese did it, then the Taiwanese, Koreans, even Hong Kong. Once they have something to lose of their own, things sort themselves out. If has been the basic pattern of intellectual property over the millennia.

    mine sounds amazing becuese its little pulse coil ferrite speaker has come loose & makes a really tragic squeaky warbling ascending & descending comical manic beeping which alters frequency dramatically when it gets near a source which really gives it some character.

    Look for the video of a radiation accident on a public bus in Bolivia from the 'Plainly Difficult' channel. If even ONE of the bus passengers had this device on their keychain, the problem would have been noticed sooner. Nor should one say that something like this couldn't happen 'here': just look at the lost Cs-137 radiation source in Australia. There are certainly some people who always carry a RadiaCode or a RAYSID with them everywhere. But that's not really practical, because these devices have to be charged much more often - they are of course also more sensitive. But having a detector like that on your keychain that you always have with you is certainly not a bad idea. Please also take a look at the ATOM-SWIFT, which follows a similar concept and is powered by a button cell.

      the HV supply is has less than 1uA of current available, so it will be barely noticeable. I know because I managed to touch the supply during the teardown process, several times in-fact. PIN diodes are not going to be sensitive enough to detect the single photon type events that is needed for a scintillation detector. I think that the BRS-02 uses a SiPM detector...

    This gadget and this review are garbage.
    Retired Certified Professional Health-Physicist here. I've spent much of my career designing and calibrating truly high range detectors such as the 1 million R/hr detector which sits in the dome of the containment of every nuclear plant in the US. It is water and air-tight. It uses graded shielding which prevents any response to beta emitters, unlike the device under test (DUT). This device should not have responded AT ALL to the Sr-90 source.
    A graded shield is designed to prevent the detector from responding to very low radiation, too weak to deliver any dose but will provoke a gross over-response in an un-shielded detector. I've constructed a shield consisting of 8 tons of pre-war* cast lead.
    Without the graded shielding, an HpGe detector will still detect the ~78 keV lead fluorescence X-Rays emitting from the shield. A graded shield consisting of a 1 mm wrap of cadmium around the detector followed by a thick foil of copper completely eliminates this response. A thin sandwich, consisting of less than 3mm will stop all the low energy radiation. Thus, a high quality GM tube surrounded by the Cd-Cu shield will not respond AT ALL to the fluorescent X-rays the electrons emitted from the Sr-90 source as they impact the nearby materials.
    This device is not gas-tight. Thus if the amateur user stumbles into a puff of Kr-85 and/or Xe-133, as from a hospital radio-medicine department, The detector will over-range long after the pulse is gone. This is because the non-sealed instrument will have filled been by the gaseous isotopes.
    I have had to demonstrate this effect to industry health-physicists at various client sites who were skeptical. The only place I have NOT had to demonstrate this effect was at one of my best clients, Three Mile Island. The reason is that they experienced this effect with high range survey instruments sent into Unit 2 on robots shortly after the incident. They had not fully realized the consequences of letting the case Neoprene gaskets deteriorate because they' never had to deal with high concentrations of Xe-133 and Kr-85.
    I had the technicians replace all the seals and we tested them again. Not a bit of leakage and thus no upscale readings after I had captured all the noble gases from my bell jar.
    While the noble gases are inside the instrument, let's examine another aspect of high irradiation inside the case. Rapid damage to electronic parts, particularly the processor and memory. The gases in direct with the processor and battery-backed SRAM quickly discharged the data stored on insulated gates of NVRAM. A discharged memory cell reads OxFF. A charged cell has a charge on the gate which means that the gate has received no radiation exposure.
    Professional instruments have external shields which allows the HP tech to zoom in fairly rapidly to the source's location. None of the toy instruments have this capability.
    Thus, I can say with great confidence that none of these toys have any use whatsoever, other than as toys. This gadget and this review are garbage.

      Actually, I didn't design my device to stick it into a working reactor with such a field intensity that the electronics themselves would crumble. And beta sensitivity was left in it on purpose. For what purpose? Try to guess.
      By the way, any detector, even the most tightly shielded from beta radiation, will react to Sr-90. Because of the braking X-rays that occur when electrons are slowed down in dense screen materials.
      End so on...

      TLDR its for the average joe to understand if something is happening or not
      Its not for anything more than piece of mind and since your retired you clearly have time to get with the times 😂

      Really -- no. To know that it's time to leave quickly or even run like hell. And it's possible to run away. In 95%-98% of possible cases.

      Your argument appears to be that because this piece of equipment does not meet your standards of measurement accuracy, the general public should not have access to it, we should rely upon the large wealthy institutions, that can make the huge equipment investments, for our own personal safety, because of accuracy issues...
      Those detectors that you worked on, how much did they cost? Even the little dosimeter you wore when on-site, is a very costly piece of kit when viewed from the perspective of the general public.
      "Time, Distance & Shielding", a mantra you will know all too well. You can't minimize any of those if you are unaware that you are being exposed at all.

      Thanks for the comment. Actually, everything in the video can legally be bought in Germany, the Cs-137 source is well below the legal activity level. Usually plutonium is is very highly controlled, but even then you often see old soviet smoke detectors that contain it being sold on ebay.

      @project-326 I heard stories from people that had a lot of uranium minerals and got problems. Even the americium source would get you in trouble afaik....I know it's stupid but it's Germany....
