ionization observed at these two positions the total value of the terrestrial gamma radiation can be derived.Both methods can also be used for determining the gamma radiation coming from the atmosphere (air radiation); however, the smallness of this effect makes it difficult to get reliable ...
Gamma rays (also called gamma radiation), denoted by the lower-case Greek letter gamma γ, are penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy. The decay of an atomic nucl...
The ability of bone substitutes to promote bone fusion is contingent upon the presence of osteoinductive factors in the bone environment at the fusion site. Osteoblast progenitor cells are among these environmental osteoinductive factors, and one of the most abundant and available sources of ...

Derivation of radiation quality average parameters in neutron-gamma radiation fields with the high-pressure ionization chamber: theory and practice. The established radiation quality parameters in mixed neutron-gamma radiation fields may be measured by applying the initial (columnar) recombination of io.....
The chamber is designed preferably for the energy ranges of photons and electrons at medical accelerators. It can also be employed in X-ray beams with generating potentials from 70 kV and for gamma radiation of 137Cs and 60Co. The energy range of proton beams with available beam quality corre...
