This papar reports the posibility of using lyoluminescence of glucose and sodium chloride pair for dose determination.
If the parameters
K
t
H
and
are known
the following equations can be used to get
in a mixed field
they are:
公式
The respones (the lyoluminescence yield) of the glucose and the sodium chloride are proportional to the absorbed dose in a given dose range.
of mixed field used for calibration have been measured with pair ionization chamber. The experiments have shown that
of the glucose is 0.304 and
of the sodium chloride
is
0.062
with
taking as 1.
