Catalogue description Home Office: Scientific Adviser's Branch: Reports (R and M Series)

Like the CD/SA series of reports in HO 225, the R and M series reports are primarily concerned with the possible threat to the civil population posed by a future war, and the consideration of measures that might be employed to mitigate the effects of enemy attack. They are mainly the work of individual scientists, and much of substance in these papers is developed further in the CD/SA series.
