Reasons to Choose Ludlum 52-1-1
Lessons from the Human Monitoring Lab
In 2012, the Human Monitoring Lab conducted an evaluation on 4 portal monitors, used for detecting radiation on humans who have been exposed. They found strengths in each of the models they tested, but noted several exemplary features of the Ludlum 52-1-1 and found it to be the ideal choice for detecting beta radiation or low energy gamma radiation.
Major Advantages of the Ludlum 52-1-1:
Easiest to Assemble and Carry
The Ludlum 52-1-1 has a very simple assembly process. Of the 4 portal monitors studied, the Ludlum 52-1-1 was found to be the easiest to assemble, requiring only one person five minutes to set up. Other monitoring units require one person ten or 15 minutes to assemble.
Carrying the Ludlum 52-1-1 unit to the assembly site was also found to be the easiest. One person can carry the Ludlum 52-1-1 in a single trip, assuming they can carry 45 kg. However, if the unit needs to be moved post-assembly, two people will probably be required!
Measures Both Gamma AND Beta radiation
The study found that the Ludlum 52-1-1 demonstrated the greatest overall capability "since it is able to measure both gamma and beta radiation." The Ludlum 52-1-1 also had a greater sensitivity to low energy gamma photons during testing, thus influencing the study to conclude that "...when beta radiation or low energy gamma radiation is suspected, then the best choice would be the Ludlum 52-1-1."
