https://physicsworld.com/a/gamma-ray-pulses-could-be-created-using-laser-plasma-accelerators/ Stimulated emission of EM radiation from radioactive nuclear isomers is another way to create pulses as well as EM ( gamma) pulses from the beta emitters. which frequently entail gammas as well. IMHO. See my earlier comment to this thread. The inert gas radioactive isotopes of krypton, radon and xenon, which are relatively long lived, may be particularly good for such stimulated emission in plasmas. I believe radioactive krypton (a fission product and beta emitter) was/ is used to light airport runways reliably. Radon, which occurs naturally from uranium decay, may be the best. Of course the beta emitters would also have an EM emission to create a pulsed emission. Nuclear fuel reprocessing routinely release the krypton to the atmosphere to diffuse around the earth and decay in time, since it is hard to control chemically. Tritium is probably a better source of betas for reliable light sources IMHO, since it is easier to control. However, a little spent fuel may work pretty well, if processed to control release of its inert gas accumulations to a plasma reactor or pulse generator.

It is demonstrated that the decrease of alpha-activity strongly depends on the peak intensity of the laser radiation in the liquid and is highest at several terawatt per square centimeter. The decrease of alpha-activity of the exposed solutions is accompanied by the deviation of gamma-activities of daughter nuclides of Uranium-232 from their equilibrium values. Possible mechanisms of the laser influence on the alpha-activity are discussed on the basis of the amplification of the electric field of laser wave on metallic nanoparticles. · Deviation from secular equilibrium<https://scirate.com/arxiv/1001.3574> A.V.

Picosecond Nd:YAG lasers at peak power from 1011 to 1013 W/cm2 at the wavelength of 1064 and 355 nm were used as well as a visible-range Cu vapor laser at peak power of 1010 W/cm2. The composition of colloidal solutions before and after laser exposure was analyzed using atomic absorption and gamma spectroscopy between 0.06 and 1 MeV range of photon energy. A real-time gamma-spectroscopy was used to characterize the kinetics of nuclear reactions during laser exposure. It was found that laser exposure initiated nuclear reactions involving both 238U and 235U nuclei via different channels in H2O and D2O. The influence of saturation of both the liquid and nanoparticles by gaseous H2 and D2 on the kinetics of nuclear transformations was found. Possible mechanisms of observed processes are discussed. · Initiation of nuclear reactions under laser irradiation of Au nanoparticles in the presence of Thorium aqua-ions<https://scirate.com/arxiv/0906.4268> A.V.

It is found that the reaction pathway depends in which water, either H2O or D2O, the laser exposure is carried out. Saturation of the liquids (H2O or D2O) with gaseous H2 or D2, respectively, enhances the nuclear reactions under laser exposure allowing their excitation at peak intensity as low as 1010 W/cm2. Enhanced gamma-activity of the probe is observed after the end of laser exposure for several hours.
