CA ON00411 MG-0002 · Fondos · ca. 1939-1995

Fonds contain material relating to operational military research from the second half of the 20th century. The documents are multi-disciplinary in nature, providing scientific, mathematical and historical perspectives of the same topic. Many documents originally come from the Public Records Office UK (PRO), now known as The National Archives (TNA). In such cases, original archival references will be provided, and potential researchers are encouraged to cite these whenever possible. For more information on these Fonds or on Ronnie Shephard, please visit http://lmharchive.ca/the-ronnie-shephard-fonds/.

An inquiry ordered by Ministry of Home Security - Research and Experiments Department. Report investigating the commonness of concussion syndrome in civilian air raid casualties by examining 904 reported air-raid casualties. Report was ordered because concussion syndrome was the most common cause to grant a Civilian War Injury Pension. It examines those who claimed to have concussion syndrome and received a pension and those who claimed to have it but did not receive a pension. Includes figures, tables and references.

Note no. ARP/291/LGS. Report for the Ministry of Home Security. The report on a test of a 1/5th scale model reinforced-concrete surface shelter to simulate a direct hit by a 250 kg. German bomb in one compartment and a near miss by a similar bomb 5 feet from the shelter's entrance. Tests were done to obtain information on the type of damage sustained to shelters in that given situation. Includes figures and photographs.
