丙氨酸剂量计是一个国际认可的技术在各种领域的辐射剂量测量。
在氨基酸丙氨酸辐射与电离辐射引起的自由基的产生(未成对电子),其中的数字是吸附在很宽的剂量范围内的剂量成正比。
的组织等效剂量计材料的结晶结构抵消自由基的重组。
一个衰落的丙氨酸产生的信号只观察到剂量值高于其光和位于一个每年百分之几的范围。

的辐射引起的测量信号的非破坏性读出的电子自旋共振(ESR)手术。
用ESR光谱仪仔细调整和由内到200kGy 2Gy范围使用适当的剂量计的剂量值可确定(3.5%,整体的不确定性在95%的置信水平)。

丙氨酸剂量计是小,结构紧凑,易于处理的。
它们的特点是低的温度的影响,湿度和剂量率以及较宽的测量范围,这使得它们适用于放射治疗,血液中的辐照装置和工业辐照设施。
由于它的高质量和低成本的剂量测定系统可以利用参考和常规剂量。

Advantages of Alanine Dosimetry
Alanine dosimetry is an internationally accepted method for
dose measurements in different radiation fields. Alanine
dosimeters are often used as reference and transfer dosimeters.
In alanine, free radicals (unpaired electrons) are generated by
ionizing radiation (gamma radiation, electrons, neutrons,
charged particles). Because of the crystalline structure, the
recombination of the radicals is limited under normal
conditions. Recombinations of a few percents per year and
hyperfine interactions of the radicals occur at dose values
above 3 kGy. Electron spin resonance spectroscopy is used to
determine the radiation induced radicals in alanine. The
measurement signal is proportional to the dose and the
dosimeter mass. The dose calculation is done by using the
peak-to-peak value of the central line or area below the
measurement signal.
Principle
_ Transfer dosimetry
_ Dosimetry in blood irradiation facilities (dose distribution,
assurance)
_ Dosimetry in radiotherapy (afterloading)
_ Dosimetry in Universities und Institutes (test irradiations/
scientific test irradiations)
_ Industrial irradiation facilities (routine dosimetry system for
assurance).
