摘要： Radiation monitoring systems for crates and containers, and small volumes of foodstuff and tobacco, and whole body animal monitoring system for measuring the radiation contamination levels of containers, foodstuff, tobacco or animals and in the case of animals particularly, livestock utilized for meat consumption. The containers or animals are weighed, identified and then directed through a specially constructed shielded holding area, wherein multiple radiation detectors measure the radiation level for the containers or animal in the pen. A microprocessor analyzes the data information and provides a respective output for each container or animal which in turn is compared with predetermined standards and input information. The particular reading per container or each animal monitored actuates controls to segregate the containers or animals by those having acceptable and non-acceptable levels of radiation. The non-acceptable segregated containers or animals are specially held for evacuation and for disposal. In case of small volumes of grocery, a small scale radiation monitoring system provides the user indication of fitness of the product for human consumption.

摘要： The gamma neutron assay technique is an alternative method to standard safeguards techniques for the identification and assaying of special nuclear materials in a field or laboratory environment, as a tool for dismantlement and destruction of nuclear weapons, and to determine the isotopic ratios for a blend-down program on uranium. It is capable of determining the isotopic ratios of fissionable material from the spontaneous or induced fission of a sample to within approximately 0.5%. This is based upon the prompt coincidence relationships that occur in the fission process and the proton conservation and quasi-conservation of nuclear mass (A) that exists between the two fission fragments. The system is used in both passive (without an external neutron source and active (with an external neutron source) mode. The apparatus consists of an array of neutron and gamma-ray detectors electronically connected to determine coincident events. The method can also be used to assay radioactive waste which contains fissile material, even in the presence of a high background radiation field.

摘要： Prior to the transportation to a discharge site of a casket or flask in which has been placed a container filled with radioactive waste, through a hole formed in the flask is introduced a probe holder (32) connected by electrical connectors (76,80) to an external measuring apparatus. The probe holder (31) is provided with a handle (68) making it possible, through a mechanism (66,56,54,50), to swing a door (42) to which a probe (34) is fixed between a retracted introduction position and a measuring position in which the probe can be oriented at 90.degree. relative to the probe holder axis. After the probe holder has been coupled by a nut (40) to a container carrier in which is located the container containing the waste, a precise, reproducible measurement of the dose rate within the transportation flask can be carried out.

摘要： The invention is directed to a method and apparatus for monitoring liquidsischarged intermittently from a discharge receptacle having a siphon. The liquids originate in a facility in which personnel work with open radioactive substances. Measurements are made of the radioactive charge of discharged liquids in the region of the siphon of each discharge receptacle to prevent contamination of the discharge path into the drainage system. If a radioactive limit value of radiation is detected which is above a specific threshold, discharge of the liquid into the drainage network is prevented. The discharge receptacles are then emptied individually and upwardly.

摘要： A beta ray flux measuring device in an activated member in-core instrumentation system for pressurized water reactors. The device includes collector rings positioned about an axis in the reactor's pressure boundary. Activated members such as hydroballs are positioned within respective ones of the collector rings. A response characteristic such as the current from or charge on a collector ring indicates the beta ray flux from the corresponding hydroball and is therefore a measure of the relative nuclear power level in the region of the reactor core corresponding to the specific exposed hydroball within the collector ring.

摘要： Apparatus for measuring gases dissolved in water using a gas exchanger to which the water to be tested can be supplied via a water feed line and a carrier gas can be supplied via a gas feed line, and wherein in addition to a water drainage line for degassed water, a gas drainage line for washed-out gas leads away from the gas exchanger, the gas drainage line communicating via a gas dryer with analysis and measuring instruments. The gas exchanger is a packed column disposed in an upright position, to which the water feed line and the gas drainage line are connected at the top and the gas feed line and the water drainage line are connected at the bottom. The water drainage line communicates with a collecting container. Communicating with the analysis and measuring instruments is a second branch of the gas drainage line for the gas no longer required, the second branch communicating with the collecting container. Branching off from the water drainage line is a sample line having an outlet tap for drawing off samples of water from which the gases have been removed.

摘要： An apparatus for detecting iodine isotopes in the exhaust gas of a nuclear installation includes a duct for a partial exhaust gas stream, which duct includes an absorption chamber which is disposed in a radiation shielding structure and through which the exhaust gas flows and which has associated therewith means for admitting absorption material and for removing it therefrom. Radiation detectors are supported in the radiation shielding structure at opposite sides of the absorption chamber for monitoring radiation of iodine isotopes collected therein, the cavity in the shielding structure in which the absorption chamber is disposed being larger than the absorption chamber and the absorption chamber being supported so as to be movable in the cavity relative to said detectors to permit calibrating the apparatus.
