良好石墨化热解石墨的高度定向样品已接受 2.5 × 1022n.v.t. 剂量的辐照。 （Dido 等效剂量）温度在 250°C 至 470°C 之间。测量了平行于和垂直于沉积平面的尺寸、密度、平行于和垂直于沉积平面的热膨胀系数以及平行于沉积平面的热导率的变化。在 900–1200°C 的温度下对相同类型但微晶完美度不同的样品以及高完美度掺杂硼的样品进行辐照，以研究结晶度和掺杂对尺寸变化的影响。
Highly oriented samples of well graphitised pyrolytic graphite have been irradiated to doses of 2.5 × 1022n.v.t. (Dido Equivalent Dose) at temperatures between 250°C and 470°C. Measurements have been made of the changes in dimensions parallel and perpendicular to the deposition planes, density, thermal expansion coefficients parallel and perpendicular to the deposition plane and thermal conductivity parallel to the deposition planes. Samples of the same type but with varying crystallite perfection, and of high perfection doped with boron have been irradiated at temperatures of 900–1200°C to study the effects of crystallinity and doping on dimensional changes.
