Abstract: A spectrometer system employs a gridless Xenon detector having an anode and a cathode supported in spaced relation from the anode devoid of structure intermediate the anode and cathode. Pulses resulting from charge collection due to radiation ionization of the Xenon gas are detected and parametrized by a computation engine through multiple detected pulses. Simultaneous determination of the position and ionization energy allows selective presentation of the data to compensate for various position dependent phenomena.

Abstract: An ionized alpha particle detector to directly measure alpha activity in ambient air that counts alpha pulses instead of measuring radon concentration is provided by an open-air ionization chamber, a means for collecting ions, a voltage source, a charging means and a means for recording alpha pulses. The ionized alpha particle detector allows the user to directly measure the alpha particle activity in ambient air and consequently, better assess the radiological public health risk from alpha particles emitted by inhaled air. The ionized alpha particle detector advantageously overcomes the difficulties in measuring alpha particles caused by oxygen ions that quickly attract electrons and form negative ions that compensate positive charged particles and prevent the formation of alpha particle pulses. The open-air ionization chamber of the ionized alpha particle detector prevents and overcomes the problems, shortcomings, drawbacks and limitations caused by oxygen ions by generating alpha pulses that can be readily detected. The present invention also provides an ionized alpha particle detector system and a method for detecting ionized alpha particles to directly measure alpha activity in ambient air.

Abstract: A very low profile ionization chamber provides increased operating current by using alpha particle emitting isotopes having low emission energies as an ionization source. The chamber includes a cylindrically shaped housing having height generally equal to a radius thereof. A conically shaped sensing electrode is carried within the housing. The housing is closed at one end by a main field electrode and at the other end by an insulating closure panel. A second field electrode is carried on the closure panel. The second field electrode also carries the ionization source. The conically shaped sensing electrode has an open central region which permits alpha particles to travel therethrough toward the first field electrode. The first field electrode could either exhibit a conical cross-section or could be planar. A chamber height on the order of 1.5 to 2 centimeters and a diameter in a range of 3-4 centimeters with a Gd148 source produces operating currents on the order of 10 pA.

Abstract: The object of the invention is a method for determining the size and shape of the radiation field (11) of an X-ray machine automatically by means of a multielectrode ionization chamber (5). By means of the method relating to the invention both the dose and the size and shape of the radiation field can be measured separately so that the ratios of the currents of the electrodes (2, 3) located in different directions in the ionization chamber (5) to the current of the reference electrode (1) provide information on the size and shape of the field, and the sum of the currents is proportional to the dose.
