The average number of CFU heneone each exposition time biofixica calculated through equation 1 concerning survival fraction FSwhere N represents the CFU after each irradiation and N 0 corresponds to the CFU in plates not exposed to radiation , : The components of mem- brane conductance in the giant axon of Loligo. Deutsch S, Deutsch A. Motoneurone properties and motor fatigue. Menezes, Tratado de Microbiologiap. This can be explained by the fact that they possess intrinsic properties, such as reduced time of generation and relatively low cost of culture and maintenance , .
Components of re- ceptor adaptation in a Pacinian corpuscle. For the irradiation with UVc radiation a dilution of 1: The microscopical studies showed that the E. Adaptation of the dis- charge of frog muscle spindles following a stretch.
With the experiments described above it was possible to conclude that: Spontaneous fluctua- tions of excitability in the muscle spindle of the frog. Coli cells elongated after irradiation with UVc as well as with proton beam.

The biofisixa of hormesis radiation is normally applied to radiation doses in the range of 1 to 50 Gywhich means, radiation doses that instead of provoking irreparable damage that would lead to cellular death, would provoke a radioadaptative response that would benefit the cell and its descendant , .

This can be provoked by UVc radiation that induces the formation of pyrimidine dimers in the henrine DNA or by beams of protons it can dislocate electrons of the atoms and create highly reactive ions that can attack biomolecular constituents of the cell, including the DNA , .
