dgosden Posted December 5, 2013 Posted December 5, 2013 Hi, Yes new joiner here currently researching X-Ray screening of military and civilians. I understand that X-Ray screening military personnel started about 1936 and that mobile units were used. So, I am looking for any information on both vehicles used and the equipment in them. This is chest X-Rays for conditions including Pulmonary Tuberculosis (TB). The Civilian mass X-Ray programme started with research about 1941 with a specialist group, under the direction of Kathleen C. Clark, reporting to the Medical Research Council in 1943/4 from which came evaluation tests on 23,000 people in central London and 3? experimental/prototype vehicles. 17 vehicles are purported to be in service in various parts of Britain by 1948. When the NHS was formed in 1948 they ordered 51 Leyland Beavers which were equipped with Watson X-Ray machines and a generator in a trailer behind. This is a wide ranging challenge so any help will be welcome .. experiences, vehicles and equipment, any surviving examples, photos and interesting info. Interest is both military and civilian. Ta muchly! ... David Gosden 1 Quote
fv1609 Posted December 5, 2013 Posted December 5, 2013 David somewhere I've got at picture of a restored civilian mass radiography unit, painted cream I think. It was taken about 30 years ago, problem is finding it! Quote
Lauren Child Posted December 5, 2013 Posted December 5, 2013 Welcome along! The Canadians had a special X-Ray truck that's listed in the Canadian Army Overseas vehicle data book. The description of the Body states "Brit built" so I wonder if it's shared in-common with the vehicles you mention? Quote
Papav66 Posted December 6, 2013 Posted December 6, 2013 There is this 1943 Bedford OY Mobile X-Ray unit that attends a few shows. Quote
fesm_ndt Posted December 6, 2013 Posted December 6, 2013 (edited) Welcome and G'Day An interesting subject. Any idea what the kv and exposure times were back in the day? This is pre Hiroshima and Nagasaki so still in the days when radiation was barely understood and shoe shops had devices to xray your feet in the shoes as a gimic. Edited December 6, 2013 by fesm_ndt Quote
dgosden Posted December 6, 2013 Author Posted December 6, 2013 (edited) Thanks for the info...yes Research and early test units were 100kV on some, 125kV on others.. exposure 0.1 to 0.15sec which requires 20kvA for just the exposure as load was in the region of 0.2A. Xray equipment was supplied by Watson, North London. Photography was the flourographic screen method screen using the Levy-West Mk39. The camera lens used was the TTH Anastigmat 50mm,'Radiography', f1.5 being the finest available at the time. Image inspection used a specially developed 35mm projector by MPP Ltd and on board film processing used the dip and dunk or spiral tank methods depending on what, I do not know. Miss Kathleen Clarke head of the Radiography section of Ilford Ltd and a world authority on the subject headed up research and development. She was awarded an MBE in 1945 for her services to mass x-ray. Sadly she died on 20th October 1968 at the age of 70 after a 4 year long stay in hospital. Cause - radiation?

dgosden Posted December 6, 2013 Author Posted December 6, 2013 Thanks and here's hoping you have luck finding the photo also keen to take a look. Some were cream and some white but have seen just one in dark blue..Might have been painted that colour by the recent owner though! Regards, David Gosden David somewhere I've got at picture of a restored civilian mass radiography unit, painted cream I think. It was taken about 30 years ago, problem is finding it! Quote
dgosden Posted December 6, 2013 Author Posted December 6, 2013 Thanks. From 1945 the UK civilian units were Leyland Beavers (pic below) but they were updated and modified until taken out of service about 1980. I think bodies remained generally the same though. Some photos and info refers to a similar trailer. See also the other posting today showing an Austin army vehicle...may be of interest. Regards, David Gosden Welcome along!

robin craig Posted December 7, 2013 Posted December 7, 2013 Interesting to see some kind of towing frame in the stowed position in front of the radiator, hardly looks beefy enough to tow that lorry. What vehicle was housed in a semi trailer or articulated lorry set up in the 70's then, I thought that was x ray? I recall seeing one at Sutton Coldfield at the recruiting place and I thought it was sold off through Withams in the late 90's. Maybe i'm loosing it. R Quote

R The frame on the front of the Beaver is for shunting the 4 wheel generator trailer. The mobile X-ray unit that used to visit military bases around this way in the 70's was based on the Bedford VAL twin steer coach chassis as I recall, as I once had to go to a barracks to sort a problem on it whilst it was operating. It from the Royal Navy at Lee-on-Solent. Quote
woa2 Posted December 7, 2013 Posted December 7, 2013 Sorting EMERs out in the Tech Archive at the REME Museum, I did find several on X-Ray machines. If you know what type of machine you need info on, there might be some info there as REME serviced them. Quote
dgosden Posted December 8, 2013 Author Posted December 8, 2013 Thanks for your post and glad to clarify the request. Little research and reporting has been done on Mass X-Ray chest screening so I and a fellow colleague are looking at the whole subject both military and civilian, with a view to publishing a report, perhaps next year. It is intended to cover equipment, vehicles, staff training and reports and results as far as is possible. It's probably easiest to note what is not required....e.g. ordinary field X-Ray equipment and vehicles. These would have been used to look at broken bones and other injuries sustained at work and in the field. Pulmonary Tuberculosis (TB) was an ever growing problem, becoming a very great concern in the 1930's. So serious was it that about 1935 the armed forces embarked on a campaign of examining personnel using mass X-Ray equipment mounted probably in vans and moving from base to base. The resulting images (on photographic film) would then be examined and those found to have, or suspected of having, a problem would then be dealt with accordingly by isolation/treatment. It should be noted that early civilian equipment was of the 'portable' type, being moved in vans and set up in buildings, offices,halls etc. The van then became a mobile photographic darkroom for processing the film and examining the images obtained by projection on a screen. Military units might have been similar. This was an early form of Mass X-Ray for later civilian use in the NHS campaign starting in 1948 although there were a few machines about prior to that year. Work by the Medical Research Council considered the methods used by the military in their study of 1942- 1944, reporting to the Ministry of Health in 1944. This resulted in the Mass X-Ray campaign which ran until about 1980. So, I my research is concerned with not just vehicles but the installed and equipment used - X-Ray machines, photographic processing and image examination equipment etc. A Time Line would perhaps be 1935 to 1950. I have now established that the generator units were the same as 4 wheel 'hippo' ? trailers fitted with a Lister JP4 power unit driving a 21kVA generator. An almost 'off the shelf' unit. Indeed, the design of civilian X-Ray van (on a Leyland Beaver chassis) bodywork was based on the military design. Chicken and egg! After about 1957 it seems generator trailers were not used - design changes, updating and X-Ray equipment changes being the reasons. So, vehicles and equipment information sought is not about 'I think you might have broken your arm sir. I'll just take an X-Ray to check' but rather the well planned and thought out mass chest X-Ray scheme for the armed forces. The attached photo is of an early NHS Leyland Beaver unit with a 'hippo' generator trailer. I would very much welcome any info about the REME Museum, equipment and archive. I hope this answers your helpful response. If not, do get back to me. And ... hope to hear from you again IDC. Kindest regards, David Gosden Sorting EMERs out in the Tech Archive at the REME Museum, I did find several on X-Ray machines.

fesm_ndt Posted December 8, 2013 Posted December 8, 2013 The other item I find interesting is that x-ray tubes, even todays metal ceramic types are extremely fragile. During the war years they would have been glass. So the storage system must be quite rugged in these trucks. Also over 90% of energy produced by an x-ray set is heat. Older medical types had rotating anodes to dissipate heat and increase the duty cycle but my guess is these trucks are prior to that idea. My guess with the fluorescent screens they may have placed the film between them as the earlier comment mentions a development process. It would be interesting to see the internal layout. Quote
dgosden Posted December 8, 2013 Author Posted December 8, 2013 Thanks. Rotating anode tubes were rejected by the MRC Technical Sub Committee as the images produced were poor compared with other types on offer at the time. Google 'viewimages' then the Getty archive 'mass x-ray' and 'oldest images'. There are several press pictures which show the equipment. But beware of the van pictures. I am pretty sure these are based on a NHS van with the Science Museum. 35mm film was used until 1957 when a change was made to 70mm and 100mm film. Leyland Beaver OPU840 (in their collection) was withdrawn from service about 1980 as an updated vehicle, not in its original pre 1957 condition or equipment. The museum model I think is dated 2001. There is an interesting report by the MRC at www.rushdenheritage.co.uk which deals with some of these things. It's the 1945 report that gives details. Considerable work had been done to find the best of the best which is why the TTH lens came to be used. The 35mm projector used for examining images was a special development too. A research contact (Dr of medicine) said that images were sometimes difficult to read. 'It was like measuring the blood pressure of a patient wearing a thick wooly jumper' because X-Rays were taken with the candidate clothed. This is backed up by extracts from other publications gleaned. There is more reading about but it needs a lot of drilling down to find reports and meaningful documents. Transport of early units, equipment etc. was done in specially made cases, 4 of which converted to a processing bench in the darkroom. I have little idea of what was used by the military as little has come back thus far. So most is based on Department of Health material. 'Hope this is of interest.

fv1609 Posted December 8, 2013 Posted December 8, 2013 Here are the Asset Codes old & new for truck & trailer mounted X-ray equipment in 1967. As for the EMERs for the vehicle mounted equipment they are in EMER MEDICAL & DENTAL O 020 - 029 Watson 90/400 man miniature radiography series 1 & 2 O 020 - 029 Unit, mass radiography Watson Odelca 70mm All other X-ray equipment & ancillaries of their various kinds are in section O.

dgosden Posted December 11, 2013 Author Posted December 11, 2013 Thanks for the reply and info... I will follow this up particularly with reference to the Leyland Beaver unit as it would seem this might be common to military and civilian vehicles. A very useful find! It is interesting to note that 70mm Watson X-Ray equipment was in use. Civilian (NHS) units changed over to this in 1957. It made for more 'readable' images. Regards David Gosden Quote
Michael anstey Posted January 27, 2021 Posted January 27, 2021 Hello in the early fifties my father drove a mass x ray unit, a leyland beaver towing a generator, a woman who was to later become my step mother, worked as a clerk, booking people in for an x ray, i went to work with him many times.

Regards, David Gosden One of these and its trailer were parked up at the rear of New Cross Hospital, Avonley Road, London SE14 where I worked in the late seventies. The hospital closed in the 80s and is now a housing 'village', I do not know where it went after closure. Quote

My dad was i/c the S E London Mass X Ray unit based out of the above New Cross Hospital in Avonley Road during the 1950s, 60s, and 70s. IIRC it closed down 1980 and he retired - prior to that the unit covered SE London out to Bromley and area but on occasion went to military establishments such as RARDE (he had been a Welch Regiment officer until 1941 when completed his training at Morriston Hospital and transfered as an RMO to North Devon Yeomanry 25pdr Field Regiment then in N. Ireland, later in Western Desert. Later a base hospital alongside the 'Sweetwater canal' S of Cairo and then back to UK as RMO Sherwood Foresters for D Day. Leg shattered in accident while loading his medical team on an LCI at Portmouth, at end of war British MO on trooping ship US Victory ship 575 SS Colorado Springs. 1960s - 70s kit based at New Cross definitely those Leyland mobile X Ray lorries and ex Army AA Lister generators, which were towed by the big Leylands, but commonly shunted into awkward locations by SWB Landrovers, which regularly and rapidly used to knock out the LR front ends.. All vehicles that old medical cream exterior paintwork.. What there was at New Cross for many years until about mid/late 70s was the original Ministry of Works X Ray vehicle, i believe of immediate postwar date, usual body with left hand side ramp for the mobile X ray set; based on Dennis Pax 5-6 ton chassis, i tried to rescue it to Woolwich Bus Museum land, but v sadly it was taken locally and scrapped suddenly one day for its 100kV inbuilt generator; had a wonderful rear interior with varnished brown wood panelling, multiple heated film drying racks and china sinks..Again iirc, i had several documents from it, and may 'somewhere' still have a leaflet from it.. dare say more info too.. 2 Quote

Ian Newitt Posted October 4 Posted October 4 I worked at a MOS factory in High Wycombe Bucks in 1957/8 and my job was to book these Leyland Beavers in for a service ,also the generator trailer where the generator was sent for servicing. We had many of these In from many areas. The company also serviced (repaired) Army Navy and Air force vehicles, trailers and coaches. 1 Quote
rupert condick Posted October 5 Posted October 5 hi not really for mass X ray, But an x-ray Austin K2Y (early model c1941) converted to an X-Ray van for munitions, (mines)? HMS Vernon. Quote
