Brayfield, A. (ed.): Martindale: The complete
Geometric progression fitting method has been used to compute energy absorption build-up factor of teeth [enamel outer surface,
enamel middle, enamel dentin junction towards enamel, enamel dentin junction towards dentin, dentin middle and dentin inner
surface] for wide energy range (0.015–15 MeV) up to the penetration depth of 40 mean free path. The dependence of energy absorption
build-up factor on incident photon energy, penetration depth, electron density and effective atomic number has also been studied.
The energy absorption build-up factors increases with the penetration depth and electron density of teeth. So that the degree
of violation of Lambert–Beer (I = I0e−μt) law is less for least penetration depth and electron density. The energy absorption build-up factors for different regions
of teeth are not same hence the energy absorbed by the different regions of teeth is not uniform which depends on the composition
of the medium. The relative dose of gamma in different regions of teeth is also estimated. Dosimetric implication of energy
absorption build-up factor in teeth has also been discussed. The estimated absorption build up factors in different regions
of teeth may be useful in the electron spin resonance dosimetry.
The operation of neutron generating tubes is presented. The real system is described. Some aspects of reversible absorption of hydrogen isotope by metals are analyzed. A model describing decisive phenomena and letting us to avoid undesirable situations is proposed. Analogies with other chemical systems are pointed out.
A method to obtain mass absorption coefficients of -articles in multielement substances is described. This method is based on a theoretical formula of the mass absorption coefficient. Mass absorption coefficient of compounds calculated by this method are in good agreement with earlier measurements and methods of computation.
