To advance the development of a radiobiological experimental set-up for alpha particle irradiations at the Arronax cyclotron, experiments were performed to get the dose response of Gafchomic EBT2 films for alpha particles at 48.3 MeV. A system has been developed using a thin monitor copper foil and an X-ray spectrometer to measure the beam intensity and to calculate the delivered dose. On the other hand, the authors have irradiated EBT2 films, with 6-MV X rays, to get the dose response of EBT2 films for photons. The dose response curve for alpha particles shows an effect of polymerisation saturation compared with the dose response curve for photons.
为推动阿罗纳克斯回旋加速器α粒子辐照放射生物学实验装置的发展，进行了实验以获取Gafchomic EBT2薄膜在48.3 MeV能量下对α粒子的剂量响应。已开发出一种系统，该系统使用薄的监测铜箔和X射线光谱仪来测量束流强度并计算传递的剂量。另一方面，作者用6-MV X射线辐照EBT2薄膜，以获取EBT2薄膜对光子的剂量响应。与光子的剂量响应曲线相比，α粒子的剂量响应曲线显示出聚合饱和效应。
