Technical approach to problems of uAP
and detection of radiation

17 April 2006, updated 26 Feb 2019

Lt. Col. John Hood, the AMC Field Engineering Officer, outlined the plan in a December 5 (1950) memorandum entitled “Technical Approaches to the Problems of UFOs.”  He proposed placing radiation counters over a wide area.  After there had been sufficient anomalous object reports to establish a pattern, the data recorded by these counters would then be compared for time and location with the sightings “to see if any change in the background (radiation) occurs with the presence of sighted objects.”  He also proposed that portable counters be made available which could be taken to the area of a sighting.  Along with the counters he proposed that an aircraft with Geiger counters and also a magnetometer be made available.  The magnetometer would indicate any fluctuations in the local magnetic field associated with sightings.  He also proposed more accurate radars capable of measuring height as well as range and azimuth.  This plan was to begin operating near the end of December.

This paper will briefly discuss a recent radiation alert, our current and past radiation recording capability, and why radiation would be an important addition to the MADAR study and UAP sightings if an operator was inclined to take part. Let me make it clear at the outset that the MADAR-III DataProbe does not have a feature or add-on module as yet but data from radiation readings can be recorded in other ways. I also want to make it clear that an operator running a MADAR unit does not have to participate in anything further unless he/she wants to as MADAR alone has considerable potential.

Mineral Lab's Radiation Network showed two regional alerts

Radiation site nodes are completely separate from MADAR nodes and are managed by Mineral Lab's world-wide network which I used along with my two-room MADAR-II system in 2014. I no longer have a Model 4 geiger counter connected to the RN because it was stolen in the fall of 2016 but I suggest that others who have MADAR sites and have or bought geiger counters that they also sign up with ML.

On February 23, 2019 at 9:27 AM (15h 27m UTC), the GMC-300-E geiger counter we purchased last year had a radiation burst of 143 cpm. This counter is not tied into the RN but monitored via a surveillance system on camera 4. To check on possible passes of radiation left over from the Japan 9.0 quake of March 11, 2011, I went to the RN Map (frame-grab above). Observe the radiation site nodes 28 and 30 on the Map in Indiana and Illinois, showing alerts right after our event here. A background increase of 2.5X is considered significant but this local event was 10X's normal and very brief.

MADAR-II's Model GMC-300E geiger counter (2018 to date)

We began using the 300-E once we moved the MADAR HQ from Mt. Vernon to Newburgh, Indiana in late 2017. You can select what you want the device to read, either in counts per minute or milliroentgens per hour. Although our 300-E is connected to a dedicated computer (an old XP) the data is not onlined to the RN but instead recorded on tape.

The screenshot shows what camera 4 sees and records. At the upper left is the activity in counts per minute and at the right the reading in milliroentgens per hour. The graph shows the last 60 seconds "pips" or clicks.

MADAR-II's Model 4 geiger counter (2014)

This is the $350 Model 4 geiger counter I bought to use with the two-room MADAR in 2014 and was online to the Radiation Network. As you can now see, a $120 GMC-300E will do the job well and can also be placed on the RN or recorded locally.

MADAR's rewired v-700

This old V-700 had been used with the original MADAR and, although plentiful, they are outdated and out of calibration.

In August of 1977, MADAR at Mt. Vernon, Indiana picked up a disturbance in the earth's magnetic field that indicated the magnet variometer had fluctuated 18 times over a period of 3 minutes and 29 seconds. The real shocker (I had thought) was that the background radation had doubled! But that wasn't the end of it. Thirty-seven years later we found that the famous "WOW"Signal occurred at the exact same time! But that's another story. In any event, background radiation could be important data as well as a change in barometric pressure. The latter data (BMP) is already integrated into MADAR-III.

For the record here is the complete file on the history of radiation and UAP, much of which comes from official Air Force files.
