Reliable dosimetry systems are crucial for radiobiological experiments either to quantify the biological consequences of ionizing radiation or to reproduce results by other laboratories. Also, they are essential for didactic purposes in the field of radiation research. Professional dosemeters are expensive and difficult to use in exposure facilities with closed exposure chambers. Consequently, a simple, inexpensive, battery-driven dosemeter was developed that can be easily built using readily available components. Measurements were performed to validate its readout with photons of different energy and dose rate and to demonstrate the applicability of the dosemeter. It turned out that the accuracy of the dose measurements using the developed dosemeter was better than 10%, which is satisfactory for radiobiological experiments. It is concluded that this dosemeter can be used both for determining the dose rates of an exposure facility and for educational purposes.
可靠的剂量测量系统对于放射生物学实验至关重要，无论是为了量化电离辐射的生物学后果，还是为了重现其他实验室的结果。此外，它们在辐射研究领域的教学中也是必不可少的。专业剂量计昂贵且难以在具有封闭照射室的照射设施中使用。因此，开发了一种简单、廉价、电池驱动的剂量计，可以使用现成的组件轻松构建。进行了测量以验证其对不同能量和剂量率光子的读数，并展示剂量计的适用性。结果表明，使用所开发的剂量计进行剂量测量的准确性优于 10%，这对于放射生物学实验来说是令人满意的。得出的结论是，这种剂量计既可以用于确定照射设施的剂量率，也可以用于教育目的。
