A 10-hour course in radiological meter reading is taught to students at the college, and a 32-hour course in radiation physics and monitoring is taught at the adult level. Marycrest College is operated by the Sisters of the Humility of Mary." This picture is from a US government archives web site. I can't remember which one. It shows a early version of a CD V-457 set in use. Note the case on the table behind the women, the old Jordan 457 (see photo below) counter on the table and the calibrated mounting board on the table in front of the Jordan 457 counter. The CD V-700s are all early Model 3s. This photo is from the CD V-457 manual. The set I have is missing several of these items. The numbered items are as follows, 1. Shipping and Storage Case. 2.Padlock and 2 keys. 3. Radiological Demonstration Unit 4. Probe and Cable assy. 6. Calibrated Mounting Board. 7. Radium Beta-Gamma sources. 8. Flat Aluminum Absorbers. 9. Flat Cardboard Absorbers. 10. Flat lead absorbers. 11. Cylindrical Aluminum Absorber. 12. Cylindrical Cardboard Absorber. 13. Cylindrical Lead Absorber. 14. Film Container 15. Instruction Manual. 16. CD V-138 Dosimeters 17. CD V-750 Charger 18. CD V-787 Food and Water Standards. Here's a photo of an early Jordan Model 457 beside a later Nucleonic Corp of America CD V-457 Model 2. The Jordan unit doesn't have a "CD V" number on it. This Jordan unit appears to be identical to the unit in the top photo. I wondered for the longest time what model of 457 was in the top photo. When an ebay seller emailed me photos of this Jordan after checking this site for info I said "let me know when you are going to auction that so I can bid on it." Here are a couple of CD V-457s. The one on the left is a Model 3A and the one on the right is a Model 2. The Model 2, 3 and 3A are all identical on the front. This counter is a table-top model that operates from a 115 volt wall plug. It uses the same probe and Geiger-Muller (G-M) detector tube that the CD V-700 uses. The Jordan unit above has the plug and probe on the back like these units. Here is the wooden CD V-457 case showing the open top tray that holds the manuals and dosimeters. The red tube on the bottom of the lid has an extra G-M tube for the counter. Right above the spare tube bracket in the lid is a holder for 2 radioactive radium beta-gamma sources. The radioactive sources weren't with this set. Here is the case with the top tray latched into the lid. The CD V-457 counter stores in the space to the left. Just in front of it is storage for the CD V-787 Food and Water Standards. Storage brackets for film reels are in the center. The dosimeter chargers on the right are sitting on top of a removable tray that holds the wooden sheilding demonstration bracket. Below that try is storage for the square sheild and tube demonstration absorbers.
