ANTON GAMMA AND NEUTRON DETECTORS ON A JOURNEY TOWARD THE CENTER OF THE EARTH. Everyday, here and a b r o a d , Anton detectors journey more than two miles toward t h e center of t h e e a r t h . They reliably provide reproducible results under severe impact and are unaffected by t e m p e r a t u r e over the range of —55°C to + 175°C. Patented Anton processes eliminate m i c r o p h o n i s m , increase sensitivity and resist t e m p e r a t u r e change. Since Anton pioneered t h e first well-logging nuclear detector more t h a n nine years ago, A n t o n halogen q u e n c h e d g a m m a detectors and BF3 neutron proportional counters have been specified by t h e oil-well logging industry as t h e " r u g g e d detectors designed for high t e m p e r a ­ t u r e and rough field u s e . " Chances are—one of the 3 0 0 some odd α, β, ν and neutron de­ tectors available from stock (or 4 to 6 week delivery) may meet your unusual environmental challenge. If not, we can help you—as we have done others—by development of detectors for your specific needs. Anton Detector data belongs in your file—send for Bulletin E2.
