透射电子显微镜用于观察α -Fe箔在总辐照剂量为5 × 10/sup 17/至1 × 10/sup 19/中子/厘米/sup 2/（中子能量高于1兆电子伏特）后的损伤。辐照在60℃下进行，在最高剂量下可直接观察到辐照损伤，以细小黑点的形式出现。然而，通过观察未辐照和辐照样品中位错的产生和移动，可以在较低剂量下推断出损伤的程度。(T.F.H.)
Transmission electron microscopy is used to observe damage in alpha -Fe foils, following irradiation of the foils to total doses of 5 x 10/sup 17/ to 1 x 10/sup 19/ neutrons/cm/sup 2/ (neutron energy above 1 Mev). The irradiations are carried out at 60 deg C. The irradiation damage can be observed directly, in the form of fine black spots, at the highest dose. The extent of the damage can be inferred at the lower doses, however, by observing dislocation production and movement in unirradiated and irradiated samples. (T.F.H.)
