This fonds contains material relating to the writing and production of four books on radiation chemistry over the period 1960 to 1994. When it appeared, An Introduction to Radiation Chemistry by J.W.T. Spinks and R.J. Woods was the first textbook in English to attempt to bring the various strands of radiation chemistry in one place. Revised editions were published in 1976 and 1990. In 1994 R.J. Woods and A.K. Pikaev collaborated to publish Applied Radiation Chemistry: Radiation Processing. In addition to illustrating the advancements in radiation chemistry over four decades, the material also illustrates the advancing technology available to scientific writers over the period 1960 to 1993.
