Most of the measurements reported here have been obtained with the 4.5-L CO2 counter previously described (Kiel I; Erlenkeuser, 1965). A few samples have been dated with a 3-L proportional counter. The copper counter is surrounded by 28 GM counters in the form of a double ring. The total assembly is shielded by 10 cm of old lead. Neither an inner lead shield between counter and anticoincidence ring nor screening of sensitive volume by a quartz tube-as in the 4.5-L counter-has been used. Background of the small counter is 17.20 cpm or The 0.95 x NBS value is 9.5 cpm at 400 torr. Within statistical error background does not depend on atmospheric pressure. The 3-L counter is placed under a concrete wall, 2.5 m in length and 9.4 m in height.

Early Results

Measurements of ionizing and nonionizing particles are performed during the rupture tests of steel rods having different diameter. A ZnS ( Ag ) alpha detector, a Geiger counter and a 3 He proportional counter for neutrons are used. From the distributions of the recorded intensity maxima, different particles emissions are suggested to occur in broken and nonbroken samples. A hint for the emission of neutrons at rupture is also obtained. Such neutron emissions are predicted in the framework of the piezonuclear theory.
