AHelium gas counter comprising a container, a gas tube within the container, and a mixture ofHelium and Xenon or a mixture ofHelium and Krypton. A method of making aHelium gas counter comprising providing a container, placing a gas tube within the container, and depositing a mixture ofHelium and Xenon or a mixture ofHelium and Krypton into the gas tube.

AHelium gas counter comprising polyethylene slabs, a rectangular gas tube within the polyethylene slabs, and a mixture ofHelium and Xenon. AHelium gas counter comprising polyethylene slabs, a rectangular gas tube within the polyethylene slabs, and a mixture ofHelium and Krypton. A method of making aHelium gas counter comprising providing polyethylene slabs, placing a rectangular gas tube within the polyethylene slabs, and depositing a mixture ofHelium and Xenon into the rectangular gas tube.

A device having: a scintillator material, an optically transparent element containing a glass or polymer and gadolinium oxide, and one or more photomultiplier tubes adjacent to the scintillator material. The optically transparent element is surrounded by the scintillator material.

Neutron detector

A method and apparatus for providing a timed, synchronized dynamic alpha or beta particle source for testing the response of continuous air monitors (CAMs) for airborne alpha or beta emitters is provided. The method includes providing a radioactive source; placing the radioactive source inside the detection volume of a CAM; and introducing an alpha or beta-emitting isotope while the CAM is in a normal functioning mode.

Dynamic radioactive particle source

An apparatus and method for the measurement of fast neutrons is described. he apparatus comprises a proton radiator with a doped glass, such as a Nd-doped glass containing ZnS:Cu. The dosimeter may be read by either laser heating or infrared stimulation of the glass or by direct scintillation. The fast neutron dose in a mixed field of gamma rays and fast neutrons can be measured by comparison of a dosimeter without a proton radiator and a dosimeter with a proton radiator.
