Abstract: The present invention is directed to a device consisting of a portable and multi-band UV light device that uses a combination of UVA, UVB, and UVC wavelength band of UV emitters.

The user can also subsequently select disinfection utilizing UVC wavelength light to sterilize the particulate collector and Instant Particulate Detector or IPD device.

Abstract: Methods, tools, and systems for determining porosity in an earth formation are disclosed. Neutrons are emitted into the formation to induce inelastic scattering gamma rays and thermal capture gamma rays in the formation. The induced gamma rays are detected at a proximal gamma detector and a far gamma detector, which are spaced at different axial distances from the neutron source. A measured proximal-to-far inelastic ratio (a ratio of inelastic scattering gammas detected at the proximal and far detector) and a proximal-to-far thermal capture ratio (a ratio of thermal capture gammas detected at the proximal and far detector) are determined and used to calculate the formation porosity. Techniques are disclosed for removing borehole and casing configuration effects from the measured proximal-to-far thermal capture ratio, leaving only porosity dependence.

Abstract: A hybrid collimated probe incorporates two detectors consisting of a scintillating crystal or semiconductor material, such as Cadmium-Zinc-Telluride (CZT). The count rate measured on the rear detector is corrected for the shielding effect of the front detector before the count rate ratio is calculated. This is done by multiplying the rear detector count rate by a factor pre-determined from the thickness and density of the front detector for a specific radionuclide energy. The count rate ratio also must be corrected for the presence of background radiation at the target site. This is done by taking a 3 second average of the count rate over tissue that does not contain a radiotracer sequestered at the site of pathology, but in adjacent tissue that is uniformly perfused by a lower level concentration of the radiotracer circulating in the blood pool background.
