Is there any method of delaying radioactive materials? Could you put some kind of liquid or gas on a radioactive material or at some temperature or electrical current that would stop the object from being radioactive?
cesiumfrog said:I suppose, by drilling holes in a bulk of material and inserting control rods or moderator, you could increase or decrease the rate of decay. In some sense this means you can freely choose the rate of stimulated decay, but there remains an apparently unavoidable* base rate of spontaneous decay, so indeed you'll still be wanting shielding.
pallidin said:Not sure, but I would guess that extreme supercooling would have a negative effect on radioactive expression.
With 11605 K /ev, the 10's of billions of K would be in the MeV range, and charged particles in the MeV range would be considered radiation.vanesch said:Not at all, in fact. Only VERY high temperatures might influence it, but I'm talking about crazily high temperatures of several tens of billions of degrees where there is thermal equilibrium with a positron/electron plasma, which might influence beta decay for instance.
No. Atomic electrons have no influence on beta decay. Take any beta emitting element and heat it, compress it or cool it, and one will get the same half-life or decay constant.Count Iblis said:E.g. in a metal the electrons occupy all the energy levels up to the Fermi energy. A beta particle emitted as a result of the decay has to have an energy larger than the Fermi energy, so less hase space is available for the beta particle and therefore the probability ewill be a bit smaller.
Stellar interiors and atmospheres are somewhat full of radiation.Count Iblis said:An extreme example are neutrons in neutron stars. The neutrons are stable because all the electron states up till the maximum energy the beta particle could have are filled (if you imagine a situation where they are not filled, then the neutrons will decay until all available states are occupied, then the decay will stop).
Astronuc said:The nuclei of atoms can be transmuted via interaction with other nuclei or high energy photons, but that means producing radioactivity in the process. Phototransmutation requires gamma-rays. Transmutation by charged nuclei or particles like protons, deuterons, . . . . requires energies in the MeV range, and as charged particle pass through matter (atoms) they ionize atoms and produce brehmsstrahlung and X-ray radiation. Free neutrons can be absorbed by nuclear matter, but usually a gamma ray is given off spontaneously after the capture, and then the nucleus would be radioactive, unless the initial nucleus happens to be 1 amu below a stable nuclide [or results in fission to rapidly decaying products].
Annie Mathews said:In an experiment with a radioactive source, different stopping materials are used. With paper, detected count increased above the value with no absorber.How do you explain this?
Astronuc said:With 11605 K /ev, the 10's of billions of K would be in the MeV range, and charged particles in the MeV range would be considered radiation.
Vanesch raised an interesting point about intense magnetic fields, but the maximum stable B is about 10-12T, and I don't think that is sufficient to influence (delay) beta decay. I am not sure why it would.

"Stop Radiation: Delaying Radioactive Materials" is a scientific approach to reducing the impact of radioactive materials on the environment. It involves implementing strategies and technologies to delay the release of radioactive materials and minimize their spread.
Delaying the release of radioactive materials helps to reduce their impact on the environment and human health. It allows time for emergency response teams to take necessary measures and for people to evacuate the affected area.
Some strategies for delaying radioactive materials include using containment structures, such as concrete barriers or underground storage facilities, to prevent the release of radioactive materials. Other strategies include using chemical agents to bind with radioactive materials and prevent their spread.
The effectiveness of this approach depends on various factors, such as the severity of the nuclear disaster, the type of radioactive materials involved, and the implementation of strategies and technologies. However, delaying the release of radioactive materials can significantly reduce their impact and provide time for proper response and mitigation efforts.
In some cases, the effects of delayed radioactive materials can be reversed through decontamination processes. However, in other cases, the effects may be long-lasting and require ongoing monitoring and management. The best way to mitigate the effects is to prevent the release of radioactive materials in the first place.
