摘要： Apparatus having reduced background for measuring radiation activity in aerosol particles. A continuous air monitoring sampler is described for use in detecting the presence of alpha-emitting aerosol particles. An inlet fractionating screen has been demonstrated to remove about 95% of freshly-formed radon progeny from the aerosol sample, and approximately 33% of partially-aged progeny. Addition of an electrical condenser and a modified dichotomous virtual impactor are expected to produce considerable improvement in these numbers, the goal being to enrich the transuranic (TRU) fraction of the aerosols. This offers the possibility of improving the signal-to-noise ratio for the detected alpha-particle energy spectrum in the region of interest for detecting TRU materials associated with aerosols, thereby enhancing the performance of background-compensation algorithms for improving the quality of alarm signals intended to warn personnel of potentially harmful quantities of TRU materials in the ambient air.

摘要： The permissable level of radioactivity due to airborne ac tinides is extremely low: the satisfactory discrimination of actinide emissions from other sources is, consequently, a problem. This specification discloses the combination of a) selecting only the larger airborne particles, b) measuring the activity of emissions at the energy characteristic of actinide decay of these particles and c) decay analysis of the measure ments to reject emissions which are characteristic of high energy processes but which have lost sufficient energy to fall within the measurement band.

摘要： A method of detecting radioactive substance in a liquid sample which comprises steps of:

1) supplying a radiation-measuring instrument containing a stimulable phosphor with the liquid sample continuously or intermittently;
2) keeping said measuring instrument in contact with the liquid sample for a given period of time to cause the instrument to absorb at least a portion of radiation energy emitted by the radioactive substance in said liquid sample; and
3) irradiating said measuring instrument with an electromagnetic wave to release the radiation energy stored in the instrument as stimulated emission, and photoelectrically detecting the stimulated emission to measure radioactivity of said liquid sample sequentially.

The method is particularly useful when employed in conjunction with liquid chromatography.

摘要： Provided is an apparatus for measuring radioactivity without loss of radioactive particles. The apparatus includes a sampler that collects a radioactive sample from an exhaust pipe, a sample detector that is provided adjacent to the exhaust pipe and includes a particle collecting filter and a first radioactivity detector, , a sample transporting pipe that extends from the sample detector and transports the radioactive sample from which the radioactive particles have been removed, a sample transporting pump that is provided at the sample transporting pipe, and a gaseous radioactivity detector that is provided at the sample transporting pipe and detects a radioactivity of the radioactive sample from which the radioactive particles have been removed. The particle collecting filter filters out the radioactive particles from the radioactive sample and the first radioactivity detector detects a radioactivity of the radioactive particles filtered out by the particle collecting filter.
