Description
таким образом, что диапазон пропускани -залирани дл энергии излучени Е ограничиваетс , т. е. по оси поглотител Xz поглощаетс излучение с энергией EZ, в то врем как на остальную часть чувствительной к излучению поверхности счетной трубки излучение с энергией EZ поступает, в основном, неослабленным .in such a way that the transmission range of the radiation energy E is limited, i.e. radiation with energy EZ is absorbed along the absorber axis Xz, while radiation with energy EZ enters the rest of the radiation-sensitive surface of the counting tube unabated.
Дл каждой энергии Е аксиальна длина Xi поглотител может выбиратьс так, что дл соответствующей энергии Е, как. следует из фиг. 2, измер етс правильна мощность дозы.For each energy E, the axial length Xi of the absorber can be chosen so that for the corresponding energy E, both. follows from FIG. 2, the correct dose rate is measured.
Фиг. 1 показывает схематически, как частичный поглотитель с соответствующими, эмпирически определенными с помощью данных по фиг. 2 /i и Xi, соединен в качестве оптимального компромисса в общий поглотитель .FIG. 1 shows schematically how a partial absorber with the corresponding ones are empirically determined using the data of FIG. 2 / i and Xi, connected as an optimal compromise into a common absorber.
Точность в 20%, котора достигаетс предлагаемым устройством в самом неблагопри тном случае и котора в основном существенно превышаетс , может рассматриватьс достаточной дл обычных измерений.The accuracy of 20%, which is achieved by the proposed device in the most unfavorable case and which is substantially substantially higher, can be considered sufficient for ordinary measurements.
Тормозное излучение, возникающее в поглотителе , пренебрежимо мало и может учитыватьс эмпирическим путем при помощи изменени величин /1 и Х.The bremsstrahlung arising in the absorber is negligible and can be taken into account empirically by changing the values of / 1 and X.
