Abstract : An attempt
is made to investigate theoretically the effect of radiation
doses
on
biological
bodies.
In
this regard,
the theoretical techniquetor the computation of absorbed energy within dielectric spherical model of human brain have been used to obtain the biologically effective
radiation dose in units of rad equivalent mammal(rem). Using the published value for dielectric properties and conductivity of human brain tissues and
the value of E2 generated
by assuming human head of 8 cm radii sphere as irradiated by plane wave, and the variation of absorbed energy with variation in human brain tissues
depth are investigated. It is found. That
energy absorbed decreases
with increasing depth of
biological bodies (i.e. in the deep muscle). Further,
the quantlzation of cellular death
has been obtained for higher
radiation doses absorbed by biological bodies,
using Poisson statistics. It is found that survival
fractions of cells decrease continuously with increasing radiation
doses.
Key words: Poissonstatistics, Specificabsorption rate. QuantizationRem.
