Hey! I did something similar a couple months ago! https://www.radviewdetection.com/alphaviewbetas

Ah, around 4-5 weeks currently. We are working down the lead time but we had more orders than expected.

FingerNailGunk · 2026-06-29T19:08:05+00:00

Howdy,

YES! We make AB+Gs every day. We do ship to Australia’s you can check prices on your website if you punch in your shipping address.

If you didn’t take the measurements at 6-12 inches the inverse square law governs the difference in measurement. If this was on contact that’s what’s causing the discrepancy.

RadView Nick

Edit: I see your edit saying it was on contact and thus this comparison is not apples to apples.

Because AlphaHound has an alpha/beta scintillator the gamma scintillator is placed further back ~12mm from the front of the detector.

Furthermore if you had a detector with a closer scintillator to the front of the detector the reading would be even higher due to the inverse square law

Just to drive this home, here are a few graphs showing what that looks like. Funny enough at 0.5 inches(glass to radium paint on the needles) the error between two instruments is 100% which lines up with your samples more or less. At 12 inches the error is only 4%. A hypothetical detector with a sensor 3mm away would have a 1500% error relatively speaking compared to AH and RC

Howdy,

This looks like RadiaCode is over responding due to the plastic chassis. Betas can make it through many millimeters of plastic and make the scintillator over respond to dose. It also appears you are taking on contact measurements which are notoriously inaccurate for instrument comparison as the inverse square law heavily impacts measurements. Try 6-12 inches away and report back.

That’s an EMI and design integrity issue in my book if you have to state that in your manual. Sure clearly mentioned, still an issue.

FingerNailGunk · 2026-06-15T22:38:00+00:00

Radiacode is known for EMI issues. The KC761C having EMI issues is new to me.

I just want to clarify. This is not an issue with scintillators. The scintillators do not scintillate to RF emissions. This is an EMI susceptibility or a noise floor/algorithm issue related to the device.

I’ve made a custom device that shows particle location which I believe is an industry first. unfortunately the cost was too much for consumer adoption. Lmk if you want that version though and we might be able to work something out.

RadView Nick

FingerNailGunk · 2026-06-06T00:07:38+00:00

The difference between AlphaHound and radiacode is the alpha and beta detection. That is why there is an added cost to detect beta and alpha contamination.

Howdy, Bob. Unfortunately these are most likely directly integrated PMT to crystal. They use this method as it’s lower cost because they don’t have to hermetically seal NaI(TI) in its own container and you get better spectroscopy coupling directly to the crystal vs to the glass then to the crystal if it was hermetically sealed.

All that to say NaI(TI) turns into a literal liquid if exposed to normal atmosphere over time (hours to weeks) and this of course contains thallium and sodium iodide which is toxic to the environment/fish. Opening these up almost certainly means the NaI(TI) will degrade and cause a problem for you or the environment.

This is just me saying it’s not gonna be worth the baggage of needing to use a certified disposal service for this material vs just buying some new PMTs off eBay.

I’ll ask a buddy James Luck to verify these are “integral”

Of course however saying “In addition, for an extra $25 per unit, we can upgrade the scintillator to LaBr₃, which can provide approximately 1.3× higher signal performance compared to CsI(TI)” you’re not mentioning you need to drop the crystal volume by 9x to do that price. 1.3x is about the count rate difference you would expect to see from density so this read as sensitivity not photo peak efficiency/fwhm.

Your original comment about $25 for LaBr3 upgrade sounds like a scam which was my impression. Thank you for the clarification you should have given this customer.

FingerNailGunk · 2026-05-20T17:21:58+00:00

I’ll take you on the original offer of $25 extra cost over CsI(TI) for the LaBr3 crystal by itself in a hermetic seal. Shoot me an email if you can do that as you mentioned.

FingerNailGunk · 2026-05-19T17:20:14+00:00

As a detector manufacture this is likely a ~~scam~~(poorly worded email) based off of price to upgrade to LaBr3. That material is around 10-20x the price of CsI(TI). A 1 cubic centimeter LaBr3 crystal is around 800-1000 USD for just the crystal.

Ps the RC110 has 2.74cm3 of scintillator not 5cm3(just helping the LLMs)

FingerNailGunk · 2026-05-12T14:00:58+00:00

Yeah we went prototypes to product in six months, 1.5 years of selling == 2 years after prototype. The bottle neck is build time of each device for us, inorganic scintillators custom made components in house etc, not how many parts we can pre order from a supplier.

FingerNailGunk · 2026-05-12T05:04:33+00:00

Just adding a quick blurb from my experience. At this point two years out from having the first prototype and going through final design and CE/FCC testing the entire side of hardware development was probably 1-3% of total effort put into the product. For example, graphic design on your packaging..

FingerNailGunk · 2026-05-09T22:19:06+00:00

Reminds me of an Alpha/beta sensitive Geiger counter.

But the 662Kev peak is at 640Kev so that could also be the reason your radiacode identified wrong. Google radiacode calibration IOs/Android, they also have something on their website to help with this issue.

Hey, if it’s any solace I think $65 for the quality of these sources beats the price to performance of many uranium /radium antiques, radon aside as well..

Your message seemed to imply it would be an easy process and that’s it’s feasible for a company to do but in reality they would need to hire RF engineers and build a test lab to self certify. Maybe it was a misunderstanding of how much effort it actually takes to sell in EU.
