利用化学方法来测量混合场中的
n
、
γ
成分已有很多方法。其中,氯代烃体系较为普遍,但方法复杂,对器皿和试剂以及操作要求都比较高;四氯乙烯化学剂量计体系则不能用于
5
00rad以下的测量;含硼与不含硼的硫酸亚铁体系也只能测量较高剂量。测量混合场中

This papar reports the posibility of using lyoluminescence of glucose and sodium chloride pair for dose determination.
If the parameters
K
n
K
t
H
n
and
H
t
are known
the following equations can be used to get
D
n
and
D
γ
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.
D
n
and
D
γ
of mixed field used for calibration have been measured with pair ionization chamber. The experiments have shown that
K
t
of the glucose is 0.304 and
K
n
of the sodium chloride
is
0.062
with
H
t
and
H
n
taking as 1.
