dissipative processes. These processes may be evaluated from formula (3)

Note-. The magnitude St
is measured
in W/cra2 -K for the processes of photosynthesis but
for the other processes S,/Av is given in J/cm2 -K. fV° is the density of absorbed power in threshold
conditions and £,
is the corresponding spectral density of absorbed power £® = lV°/Av.
It should be remembered that to obtain
correct evaluations of St
the S, values
must be calculated starting not from the characteristics of the incident radiation but
from those of the absorbed radiation if the width of the absorption spectrum
is narrow-
er than the width of the acting
radiation. For
the reverse ratio of bands St must be
considered from
the spectrum of the elementary excitations
in the system
[4]. The
Table gives the S, evaluations for a number of processes of interaction of electromagnetic
radiation with biological objects.
The processes and systems included in the Table are so chosen as to demonstrate
how wide is the range of values of the dissipative functions in different biological objects.
It gives the evaluations of the dissipative functions both for processes the characteristics
of which do not cause any doubt (human vision, plant photosynthesis) and for effects
the very existence of which is of a debatable nature (bioresonance effects of u.h.f. ra-
diation). Since the characteristics S, and S, essentially depend on the frequency charac-
teristics of the effect then for the three last processes presented in the Table later experi-
ments may introduce the most significant correctives.
As shown in
[2] together with S,
it
is desirable to use the magnitude SJS, which
being dimensionless
is a more graphic
characteristic.
Its physical meaning
is simple
showing as
it does by how many times the rise in entropy as a result of thermodynamic
irreversibility exceeds the rise in the entropy of the system through absorption of elec-
tromagnetic radiation and so characterizes the degree of perfection of the energy trans-

most perfect

In other systems SJS^l and for the processes of interaction of u.h.f. radiation with
biological objects this ratio may reach 108

It is shown that during oxygenation of the blood the permeability of erythrocyte membranes
.for oxygen falls at least ten fold.
In [1] it was shown experimentally that on oxygenation in certain conditions of different
volumes of donor blood the curves of the dependence of the degree of oxygenation *
on the oxygenation time t in the coordinates a-log t may be combined with an accuracy
±2% by shifting along the log t axis. This means
that the link between the degree of
