A Look Back in Time 

  In today’s post 911 world the older among us remember when the threat to the country was not to any area of the country at a time but to the entire country at once.  Today even if terrorists succeeded in detonating an atomic weapon or dirty bomb, this would result in casualties only within the weapon’s lethal radius.  As awful as this is, we must remember that during the height of the cold war a nuclear exchange between the U. S. and the U. S. S. R. would have killed most higher life forms on the earth.  Even with an accidental limited nuclear exchange the casualty rate would have been horrendous.  Those killed in the initial blast would only be the beginning of the carnage.  The radioactive fallout from these weapons would kill many more than the initial blast.  To mitigate the casualties from nuclear fallout, the government put into place a civil defense plan in the 50s that included radiological survey meters to detect this invisible menace and trained personnel and provided temporary shelters so more people could survive.  Booklets were distributed to the public to inform them of these efforts and the public was encouraged to build shelters and stock materials.

Radiological Survey Meters

  President Truman signed the legislation that created our modern civil defense program on January 12, 1951.  Early attempts to get the states to acquire radiological measurement instruments by the Federal Civil Defense Administration (FCDA) was a failure so instruments were purchased and loaned to the states for personnel training but when these were returned most states still did not purchase their own instruments.

  It was not until 1960 that the Federal Government issued grants to the states for 100,000 radiation monitoring stations (later 150,000). The following meters were approved:

  CDV 700 ~ low range meter 0-50 mr/hr.

  CDV 710 ~ high range meter 0-50 R/hr.

  CDV 715 ~ high range meter 0-500 R/hr.

  CDV 720 ~ high range meter 0-500 R/hr. with beta particle detection capabilities.

  CDV 717 ~ high range meter 0-500 R/hr. with a remote sensor and 20 ft. of cable.

  CDV ~ 730  CDV ~ 740  CDV ~ 742  wearable personal dosemeters.

  CDV ~ 750  dosemeter charger

  The CDV ~ 710s and early CDV ~ 720s were decommissioned (disposition process) by the government in the early 60s.

The earlier meters used vacuum tubes and had "B" batteries.  This made them obsolete when transistor models could use just "D" cells.  The late 720s and the 715 and 717 used a vacuum tube but had a transistor power supply that supplied the plate voltage.
