16	Method for the quantitative determination of the fissile material content in small size particles	US09555491	2000-06-01	US06459747B1	2002-10-01	Jacobus van Geel; André Lagerwaard
A method is provided for the quantitative determination of fissile material content in small size particles present in samples. The samples are sandwiched in organic sheets and then submitted to a defined thermal neutron fluence whereupon fission products of the fissile material in the sample create in the sheets fission tracks which are rendered visible by etching the sheets. Then the size of selected particles having created such tracks is. determined by means of a microscope and thereafter these visible tracks of the selected particles are compared to pre-established standard tracks obtained by the same process from particles of different stepped known size and enrichment ratio.
17	Track registration detector for radon concentrations	US703611	1991-05-21	US5132535A	1992-07-21	Daniel J. Steck
A detector for radon concentrations is provided having a housing, a cover member and a track registration device. The housing has a groove defined by a base, an inner wall and an outer wall with the inner wall and the outer wall extending from the base. The cover member has a side wall and is supported on the housing. The side wall intersects the groove thereby forming a U-shaped channel. The U-shaped channel creates a path for entry of radon concentrations from an exterior of the housing to an interior of the housing. The track registration mechanism is supported entirely within the housing and is capable of developing tracks thereon caused by radon-generated alpha particles.
18	Automated scanning of track recorders having variable track density	US274850	1988-11-22	US4900935A	1990-02-13	James H. Roberts; Raymond Gold
A method is presented to scan fission tracks in solid state track recording material that provides a high degree of accuracy. Three separate methods of estimating true track density are used, each in its range of greatest reliability. The first method for low track density directly observes tracks and counts them. The second method for ranges of medial track density uses the Buffon needle method of determining the probability of track pile up to determine true track density. The third method, which is applicable at high track density, measures the amount of transmitted light to determine the opaque track area and relates this to true track density. The three methods are complimentary to each other and one of the set is automatically applied to any measured areal unit. The method is applied with known apparatus.
19	Solid-state track recorder dosimetry device to measure absolute reaction rates and neutron fluence as a function of time	US72776	1987-07-13	US4874951A	1989-10-17	Raymond Gold; James H. Roberts
A solid state track recording type dosimeter is disclosed to measure the time dependence of the absolute fission rates of nuclides or neutron fluence over a period of time. In a primary species an inner recording drum is rotatably contained within an exterior housing drum that defines a series of collimating slit apertures overlying windows defined in the stationary drum through which radiation can enter. Film type solid state track recorders are positioned circumferentially about the surface of the internal recording drum to record such radiation or its secondary products during relative rotation of the two elements. In another species both the recording element and the aperture element assume the configuration of adjacent disks. Based on slit size of apertures and relative rotational velocity of the inner drum, radiation parameters within a test area may be measured as a function of time and spectra deduced therefrom.
