Radiation damage to plants through X-ray exposure has been reported to impair root growth. The literature on the critical dose for growth impairment is inconclusive, partly as dose measurements in soil are scarce. Here we fill this gap and show that the dose in a typical single pot scan amounts to 1.2 Gy. In addition, we demonstrate the shortcomings of estimating the dose from scan settings using the RadPro Calculator and highlight the efficient reduction of X-ray exposure by a lead shield.

在土壤中测量 X 射线计算机断层扫描引起的辐射剂量

据报道，通过 X 射线照射对植物造成的辐射损害会损害根系生长。关于生长障碍临界剂量的文献尚无定论，部分原因是土壤中的剂量测量很少。在这里，我们填补了这一空白，并表明典型的单锅扫描中的剂量为 1.2 Gy。此外，我们展示了使用 RadPro 计算器根据扫描设置估计剂量的缺点，并强调了铅屏蔽可有效减少 X 射线暴露。
