Detection and measurement The ionizing or excitation effects of beta particles on matter are the fundamental processes by which radiometric detection instruments detect and measure beta radiation.
Being composed of charged particles, beta radiation is more strongly ionizing than gamma radiation.
Curium-243 with a ~30 year half-life and good energy yield of ~1.6 W/g could make for a suitable fuel, but it produces significant amounts of harmful gamma and beta radiation from radioactive decay products.
Beta radiation from linac accelerators is far more energetic and penetrating than natural beta radiation.
Gamma radiation, however, is composed of photons, which have neither mass nor electric charge and, as a result, penetrates much further through matter than either alpha or beta radiation.
In water, beta radiation from many nuclear fission products typically exceeds the speed of light in that material (which is 75% that of light in vacuum), The macroscopic speed of light in water is 75% of the speed of light in a vacuum (called "c").
