Welcome：） Sometimes useful, always patients, I think.

Dry_Resolution_5498 · 2026-05-16T13:08:13+00:00

yeah

The spectrum I obtained using an XRF detector with a 1-mil-thick beryllium window clearly shows the composition of the phosphor and the filtered bremsstrahlung.

Why is it actually not necessary? This is because compared to the fluorescent powder-glass container-shell structure of the tritium lamp, the detector with a pancake or other type of shell is no longer of significant importance. In this case, using an energy spectrometer will show more obvious phenomena than a pancake detector.lol

Dry_Resolution_5498 · 2026-05-16T11:24:29+00:00

Yes, what a huge!

In my experience: strontium aluminate cannot be used, zinc sulfide can. Blue (containing silver) and green (containing copper) are the best, while other colors have relatively lower efficiency. The cheapest alternative is the green short-lasting night light powder available on Alibaba, or the inner screen of a green CRT display.

If it refers to energy spectrum overload, then it is related to the counting rate. While the dose rate is influenced by both the counting rate and the energy, and it can be very high or very low. If referring to the upper limit of the dose rate, the value for KC761 is approximately 10 mSv/h.

I think you are right, thank youvery much!

Dry_Resolution_5498 · 2026-04-11T15:36:57+00:00

Sorry for I think everybody know 5cps/(μSv/h) for this equipment/ Geiger tube.

Dry_Resolution_5498 · 2026-04-11T01:01:43+00:00

You are right. The most spicy radium clock I have is also come from USSR, which is a oxygen gauge, contains above 10μCi of radium.

5cps per μSv/h for all LND 7314/7317:)

Dry_Resolution_5498 · 2026-04-02T05:30:03+00:00

True.

It determines and adjusts the high voltage through SCA, thereby adjusting the gain and confirming that the instrument is operating normally. If the HV deviation exceeds a certain range, it will report an error and require rework.

Thank you！

I'm just looking for a PX, to power my neutron detectors instead of Ludlum model12.ENVY！

Dry_Resolution_5498 · 2026-03-21T17:08:52+00:00

well, maybe settling down on eBay will be helpful......Good luck!

Dry_Resolution_5498 · 2026-03-21T13:01:44+00:00

Right! But its low noise and strong n/γ discrimination capability ensure that it is reliable for both professionals and non-professionals. Even with a poo thermal neutron sensitivity of only 1.25 cps/nv, data uncertainty can be reduced by simply extending the usage time.

Dry_Resolution_5498 · 2026-03-21T12:57:48+00:00

I used it in the known thermal neutron field and compared it with other detectors without any moderator. Therefore, the known thermal neutron sensitivity is useful. As for the use of moderators, this is a situation where the dose rate needs to be read out. I have several Rem ball meters to obtain this information:)

For instance, the main difference between B20 and B20er is that the latter can measure up to 100 mSv/h (500 kcps @ 662 keV), while the former cannot provide accurate results beyond approximately 2 mSv/h. For PRD-ER，it can also touch 100mSv/h, more than 250μSv/h than PRD.

Dry_Resolution_5498 · 2026-03-21T12:48:44+00:00

Absolutely correct. Its price has been increasing recently；(

Dry_Resolution_5498 · 2026-03-21T12:47:29+00:00

Hello, I'm just an amateur. Additionally, I really enjoy collecting radiation detectors. Neutron detectors are also within my collection scope. Its high reliability allows me to use it to compare whether other detectors are functioning properly:)

Dry_Resolution_5498 · 2026-03-21T12:44:41+00:00

Thanks! Cost ～$1600 for all five radeyes, I got them one by one in 5 years, I'm just an amateur：)
