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*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*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*****，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。

Harwell Radspin

Harwell RadSpin

When pellets containing the amino acid alanine are irradiated, stable free radicals are produced in conce*ation which depends on ex*ure.

The measured resp*e to microw*es of the pellet placed in a manetic field of a paramagnetic resonance spectrometer, is quantitively related to the radiation dose which the pellet absorbed.

Dose Range

Radspin has a functional dose range of 0.1 kGy to 70 kGy (0.01 kGy to 100kGy may also be achieved) which makes it idea for almost any range of irradiation processes.
