If we have a beam of photons and a beam of protons with the same energy, which one will get further inside the human body?
If we have a beam of photons (high energy X-ray) and a beam of protons both with the same energy, which one will get further inside the human body and why? Can this be explaind due to LET (Linear ...

What is the importance of excited states in the emission of gamma radiation during alpha decay?
Let's suppose that during a hypothetical alpha decay of a nucleus X, has two excited states (such as 2.3 mEV and 0.9 mEV) are respectively fed.
The question arises here: what would would be the energy ...

How does Neptunium-239 gain an electron after Uranium-239 beta decays?
I'm reading Richard Rhodes' book on the creation of the atomic bomb, and and we've reached the point of creating Plutonium by bombing U-238 with neutrons. I understand how U-238 absorbs a neutron and ...

How do radiation particles escape the atom unaffected in radiation?
Alpha radiation is the emission of two protons and two neutrons from the nucleus of an atom (helium nucleus). Beta radiation is the emission of a high-speed electron from the nucleus of an atom as a ...

What radiation spectra does neon glow at 2500 K?
A neon gas tube, when passed with high voltage electric current, will emit a characteristric spectrum of color.
This spectra lines are explained by the different combinatorial paths that electrons ...

Why does beta-plus decay (positron decay) have a 1.022 MeV energy requirement rather than 0.511 MeV + the binding energy of an electron?
From my understanding, beta-plus decay is only possible when certain energy requirements are met due to the fact that the atom will need to emit a positron particle, which has a rest energy-mass ...

Find the maximum possible energy for a beta-particle decay-chain [closed]
So I have this problem where I'm supposed to find the maximum possible energy for a $\beta$-particle in the following decay-chain:
The first decay:
$$^{90}Sr\rightarrow ^{90}Y + \beta^- + \bar{v}_e$$

What would happen if an atomic bomb exploded on a nuclear power plant?
Would the effect be different than if the nuclear power plant were bombed with traditional explosives?
Would the atomic bomb neutralise any potential radioactive effect of the obliteration of the ...

Is all transformation of quarks and neutron happen for $\beta^+$ decay?
In the video, the person had said "when proton comes in" they form neutron, positron and neutrino. I was thinking what he meant by "comes in". Was he talking about any kind of ...

Why does the product nucleus lose an electron during beta positive decay process?
The question describes the beta positive decay for Nitrogen-13 into Carbon-13.
After reading the explanation for the answer, it says that carbon ion will lose an electron in the decay process; ...

Why do atoms only absorb energy in the form of radiation or heat?
Why do atoms eject electrons only if they are provided energy in the form of radiation(photons) or heat(thermal energy or friction)?
Why can't we excite atoms by increasing its other energies like ...

How to calculate the mass difference from beta decay of Carbon-14?
I want to calculate the energy released from the beta decay of Carbon-14:
$${}_6^{14}\mathrm{C} \longrightarrow{}_7^{14}\mathrm{N}+{}_{-1}^{0}\beta+\overline\nu$$
The following masses are given:
${}_6^...
