摘要： A radon detector including a base portion, a cover portion, and a shield arrangement. The cover portion attached to the base portion houses a contained gas volume and allows diffusion of gas between a surrounding into the contained gas volume. The base portion has at least two detector location areas, enabling mechanical arranging of nuclear track detector means. The shield arrangement includes at least one shield and a shield actuator arranged for moving the shield between a closed and an open position, for each of the detector location areas. Thereby, the shield in the closed position prevents a line-of-sight between the contained gas volume and the detector location area. The shield in the open position allows a line-of-sight between the contained gas volume and the detector location area. The shield actuator is controllable from outside the contained gas volume.

摘要： A continuous alpha monitor includes an air intake mechanism, which in turn includes an air mover and an air flowrate monitor, an air intake prefilter that limits particulates in the air intake mechanism to an aerodynamic diameter of 10 microns or less, and a particle size detector mounted downstream of the air intake prefilter, the air particle size detector providing a distribution of aerodynamic diameters of particulates in air passing the prefilter, the particulates including depleted uranium particulates. The monitor further includes a sample filter mechanism that collects the particulates; a detector mechanism that detects alpha radiation emitted by the collected particulates; a dust loading mechanism that computes a dust thickness on the sample filter mechanism; and an output mechanism that provides an indication of alpha concentration detected by the detector mechanism.

摘要： A method for increasing a detection sensitivity of a radon monitor based on an electrostatic collection method and a device thereof increase the detection sensitivity of the radon monitor based on the electrostatic collection method through increasing a collection efficiency of positively charged 218Po in an internal cell of the radon monitor based on the electrostatic collection method. A metal mesh is provided between a wall of the internal cell and a semiconductor detector to increase an electric field intensity close to the wall of the internal cell. A ground wire of a high-voltage module is connected to a surface of the semiconductor detector. High-voltage outputting wires of the high-voltage module are respectively connected to the wall of the internal cell and the metal mesh, in such a manner that high voltages are respectively outputted between the wall of the internal cell and the metal mesh and between the metal mesh and the surface of the semiconductor detector. Because the electric field intensity close to the wall of the internal cell is increased through directly increasing the voltage between the wall of the internal cell and the metal mesh, once the voltages between the wall of the internal cell and the metal mesh and between the metal mesh and the surface of the semiconductor detector are adjusted to appropriate values, a collection efficiency of an electrostatic field to the positively charged 218Po is increased.

摘要： An apparatus and an analytical method for detecting and measuring alpha particle emissions from liquid samples using direct detectors. The apparatus may include a partition that is vapor-impermeable and alpha-permeable such that vapor from the liquid sample is substantially or entirely prevented from escaping through the partition, while alpha particles are able to escape through the partition for detection. The method may offer improved accuracy, flexibility, and quality in detecting and measuring alpha particle emissions.

摘要： A light detecting unit of an alpha ray observation device observes an alpha ray by measuring generated light that is generated by the alpha ray produced in a region of a to-be-measured object. The light detecting unit has a travel direction changing unit that changes the direction of travel of generated light, a light detector that detects direction-changed light, which is the generated light after the direction of travel is changed, and a shielding member that shields the light detector from radiation and has a portion that is provided on the line from the to-be-measured object to the light detector. The shielding member may also surround the perimeter of the light detector and have an opening to allow generated light to reach the travel direction changing unit.
