First edition, first impression. 86pp, with occasional monochrome illustrations. Laminated stiff card covers. 8vos. Covers are heavily rubbed at edges, with lifting corners (dog-eared), some indentations and bumped at spine base. An ex library copy with a stick on the front panel, usual library markings inside front cover and on title and copyright pages, and last two leaves. Two pages (title page and last leaf) have been corner clipped, not affecting text), and some minor signs of handling internally.
Not a pretty copy but good working/reference copy of this now hard to find title on nuclear energy.
