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.

摘要:
A method and apparatus for determining the power, momentum, energy, and power density profile of high momentum mass flow. Small probe projectiles of appropriate size, shape and composition are propelled through an intense particle beam at equal intervals along an axis perpendicular to the beam direction. Probe projectiles are deflected by collisions with beam particles. The net beam-induced deflection of each projectile is measured after it passes through the intense particle beam into an array of suitable detectors.

摘要:
Tensioned metastable fluid detectors are disclosed that minimize false positive detection events. The methods involve the use of new fluids that provide improved neutron-alpha fission detection at reduced tension states. The rate of spin is also increased using a new protocol that avoids the creation of liquid imbalances in the arms of a CTMFD (centrifugally tensioned metastable fluid detector). The disclosed CTMFD radiation detection system includes a detector assembly containing a detection fluid, a base, a safety enclosure, a motor and motor mounting bracket, speed sensors, a cooling system that includes an air inlet and outlet and a safety enclosure. The CTMFD radiation detection system can include a plurality of independent detector arms having fluids with distinct Pneg requirements such that the range of detectable radiation is increased. Also disclosed are methods for detecting radiation using the disclosed CTMFD radiation detection system. Motor speed calibration procedures are also disclosed.

摘要:
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.
