Samuel T. Glasstone’s
An Introduction to Nuclear Weapons
Revealed

Samuel T. Glasstone, who wrote the unclassified The Effects of Nuclear Weapons from 1950-1977, also authored several other books for the US Military, which remain tightly classified, even to this day.

From May 1999 to December 2002, a Department of Energy declassification review was conducted on one of his secret works; An Introduction to Nuclear Weapons, which was published in 1962, 1963, and 1972.

These reviews kept most of the books classified, unfortunately. Here are the editions which were reviewed and what was allowed to be released in sanitized form:

An Introduction to Nuclear Weapons by Samuel Glasstone (March 1963).

Unique Document #:SAC200117610000

Notes: Chapter 3 through 8 were withheld in their entirety, along with the index. Significant bits of information in what was released was sanitized, like the minimum critical masses of reflected spheres.
Random things noted from skimming it:
● It says that as a result of spontaneous fission, U-235 emits on ordinary about 0.85 neutrons per kilogram per second, while U-238 emits 17 neutrons per kg/sec. So the neutron background of ordinary Oralloy (93.5% weight U235) is about 2 neutrons kg/sec.
● It says that the spontaneous fission rate of plutonium-240 is about 440 fissions per second per gram, and since 3 neutrons are liberated per fission, this means that 1 gram of Pu-240 emits well over 1,000+ neutrons per second.
● It also says that in modern boosted implosion type fission weapons, the cores are hollow sub-critical shells that contain deuterium-tritium boosting gas.
