British Civil Defence Instruments
The United States manufactured approximately 500,000 geiger counters. Britain manufactured about 20,000 of each of its major types, and is second after the U.S. Some instruments were also manufactured by other countries in smaller numbers.
The American instruments dating from the Kennedy administration era were designed to use low voltage transistor electronics, and the batteries are still available today. However, most British civil defence instruments retained until 1982 or later were manufactured from 1953-7, and required high voltage batteries which became obsolete after portable valve radios were superseded by transistor ones.
All British civil defence instruments were jointly designed by the Home Office and the Ministry of Defence, and were also a military issue.

“The great British Library—an immense collection of volumes of all ages and languages, many of which are now forgotten, and most of which are seldom read: one of these sequestered pools of obsolete literature to which modern authors repair, and draw buckets full of classic lore, or “pure English, undefiled” wherewith to swell their own scanty rills of thought.”
—Washington Irving (1783–1859)
“[Rutherford B. Hayes] was a patriotic citizen, a lover of the flag and of our free institutions, an industrious and conscientious civil officer, a soldier of dauntless courage, a loyal comrade and friend, a sympathetic and helpful neighbor, and the honored head of a happy Christian home. He has steadily grown in the public esteem, and the impartial historian will not fail to recognize the conscientiousness, the manliness, and the courage that so strongly characterized his whole public career.”
—Benjamin Harrison (1833–1901)
“There can be no defence like elaborate courtesy.”
—E.V. (Edward Verrall)
“The worth of a State, in the long run, is the worth of the individuals composing it ... a State which dwarfs its men, in order that they may be more docile instruments in its hands even for beneficial purposes—will find that with small men no great thing can really be accomplished.”
—John Stuart Mill (1806–1873)
