My question is: given a source of Iridium 172 with a certain activity, what is the distribution of gamma emission, I should expect? It's pretty straightforward, to find easy decay schemes for some ...

This is just a mini tesla coil exciting an Eisco neon discharge lamp. The detector is a MightyOhm geiger ++ which detects beta and gamma radiation. I'm recording 30-60 CPM just with background ...

The detection of exceptionally high-energy $\gamma$-photons (up to 18 TeV) from GRB 221009A by the LHAASO Collaboration challenges conventional physics. Photon-axion-like particle (ALP) oscillations ...

I am a beginner in the world of gamma spectroscopy. I have been preforming spectrum analysis on samples of mainly Ar-41, although I do not think the existence of Ar-41 specifically in the sample is ...

Why don't we use gamma rays to probe proton structures just like a super optical microscope? Is it because real photons are on shell and can't receive enough transverse momentum transfer?

Why can $γ$-rays and X-rays have the same wavelength and frequency? X-rays have wavelengths between $10^{-8}\,\text{m}$ to $10^{-13}\,\text{m}$ while $γ$-rays have wavelengths from $10^{-10}\,\text{m}$...

The data is below. It is from the paper here, https://www.mdpi.com/2075-4701/10/8/992 I am surprised that the nuclear line width is even smaller than the atomic line width. I would expect the line ...

I want to estimate the depth and strength of a buried radioactive source. The drop off is governed by the inverse square law. If a very strong source measures 5uSv/hr at the surface because it's deep ...

When an X-ray or a gamma ray strikes a memory cell like in DRAM and causes electron-hole pairs to be created due to effects like ionization of electrons or transferring energy into the electrons, is ...

Is it possible for a ray of light, or even a single photon, to 'break' the vacuum of space? If so, at what energies (in eV, e.g.) would this happen?

I understand that beta and gamma emissions are what makes the decay of a radioisotope dangerous. However, U-238, which is what SNF is mostly made of, doesn't emit gamma or beta particles frequently ...

I was looking at an info table for radionuclides, and it said that for F-18, the 511keV gamma rays have a 1st half-value layer of 7mm, and a 2nd half-value layer of around 4mm (Edit: in lead). Why is ...

I'm trying to found a comparison of the energy received on Earth by GRB 221009A in comparison of various solar flares based on NOAA Space Weather Scales (or other). I failed to find any comparison (...

This might be a stupid question, but, why is it that gamma rays are able to penetrate almost any barrier without question? We know that gamma rays are simply high frequency waves with massive amounts ...
