Nuclear Physics
Most commonly known for its applications in nuclear energy and nuclear weapons, Nuclear Physics also has applications in medicine and archaeology. This category is for questions about the branch of physics that deals with the study of the forces, reactions, and internal structures of atomic nuclei, Nuclear Physics.

What is the formula that will balance this alpha decay equation 223 Fr æ?
87Fr223 ----> 2He4 + 85At219
Why don't Jamaica have nuclear weapons?
Nuclear weapons are very expensive. Jamaica does not have nearly the kind of economy that permits the building or purchase of such expensive weapons. And nobody is going to invade Jamaica anyway. Jamaica does not need nuclear weapons.
No. It is an alternative to fossil fuels and is not exhaustible in real terms. It offers the best reduction in CO2 of anything out there, but is not a renewable.
What is radioactive decay caused by?
Is the process by which the atomic nucleus becomes slightly smaller, as a result of the emission of particles, electromagnetic radiation, or both. ELECTROMAGNETIC FORCE is the right answer
What can penetrate paper but not a thick sheet of aluminum?
My hand can penetrate paper because of the force of your
fist it will cause a devastating reaction that will happen in
split second because of your bone structure..

You think probable to beta radiations.
What Is the relationship between a Higgs boson and an atom?
The Higgs boson is analogous to other bosons (photon, muon, gluon, graviton, etc.) which couple forces.
Atoms are composed of fermions bound together by exchanging various virtual bosons (e.g. electrons are bound to the nucleus by exchanging virtual photons, the protons and neutrons in the nucleus are bound together by exchanging virtual muons, the quarks are bound inside protons and neutrons by exchanging virtual gluons), no real bosons of any type exist in an atom (although some atoms are themselves bosons even though they are entirely composed of fermions).
How long will it take 600 grams of Plutonium to decay on 18.75 grams?
Each isotope has another half life.
What high school will a nuclear physicist go to?
Probably the same one the rest of us go to. It will be in college when he/she will select a speciality.
In 1939, J. Robert Oppenheimer was the first to realize that an atomic bomb could be made as a result of nuclear fission. Prior to this, there were several scientists around the world who knew they were on the verge of discovery. It wasn't until 1945 that the first experiment was conducted.
What happens when U-235 emits a beta particle?
beta decay results from the transformation of a neutron in the nucleus to a proton (+ charge) and an electron (beta particle). The proton remains in the nucleus increasing the atomic number by one (mass number remains the same) while the electron is emitted as a beta particle. So, U-235 of atomic number 92 changes to Neptunium with atomic number 93.
However, to my knowledge, U-235 decays by gamma not beta. U-236 decays by beta to Neptunium-236.
What is the ratio of the mass proton to the mass of an ELECTRON?
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.
Is there a method of measuring radioactivity from a satellite or from a remote distance?
i don't know but for sure their must be some method to measure the radioactivity from distance.
and fist of all radioactivity is phenomenon in which radioactive elements emit some rays so the intensity of those rays can be measured from the distance
What region of an atom has all the weight?
No region has all the weight, but the vast majority of the mass of an atom is in the nucleus.
Why radioactive has prefix radio?
The term radioactive comes from Madame and Pierre Curie, who combined the Latin term radius, meaning beam of light, and actif, meaning, active.
Its not a prefix, its simply part of the word.
Did little boy bomb involve the splitting of only one single atom?
No.
The bomb was so named because the design of the bomb was based on two semi-spherical hemispheres colliding together on impact. The bomb required a longer design to accomplish this task.
Fat man, on the other hand involved an implosion detonation device, which resulted in a lager bomb. (In Girth)
Interestingly both bombs were a 20 KT yield.
How was roentgenium discovered?
The first nuclear reaction used to obtain roentgenium was:
20983Bi + 6428Ni = 272111Rn + 1 n
In the years 1974, 1975, 1976 in North East Ohio, USA...this word CLEARLY meant very much under the influence of recreational drugs. Remember the World Series of Rock?

Which one is the lasing material in helium neon laser?
The lasing material in a helium-neon laser is a mixture of helium and neon gases. The neon gas is responsible for emitting the red laser light when excited by the helium gas.
Activity of an isotope is measured in Curies and Becquerels?
Yes.
A Curie (Ci) is 3.7 x 1010 disintegrations per second, and corresponds to about 1 gram of Radium-226.
A Becqueral (Bq) is 1 disintegration per second, corresponding to about 2.7 x 10-11 Ci.
Also used is the microcurie, µCi, which is about 2.22 x 106 disintegrations per minute, corresponding to about 10 times the normal amount of Potassium-40 contained in a human body.
How does a PET Scan use Radioisotope decay?
A PET scan uses radioisotope decay by detecting the pair of annihilation photons emitted during the decay process.
It takes 4 half-lives for something with 400 cps to decay to 25 cps. The half-life of 131I is 8.0252 days, so it would take four times that, or 32.1008 days for this to happen.
