D2. State-of-the-Art Long-Range Alpha Radiation Detector.

D2. State-of-the-Art Long-Range Alpha Radiation Detector. Alpha radiation is notoriously difficult to detect even within inches of the source. This machine, developed in the 1990's, represents a breakthrough in alpha radiation monitoring. It was invented at the Los Alamos nuclear weapons laboratory. It can register trace ions formed in air by alpha particles at a distance of several meters. It cannot, however, detect alpha radiation inside the human body. Los Alamos, New Mexico. 24 February 1994.
