Abstract
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.
Claims14
A method of measuring an alpha particle emission level from a liquid sample, the method comprising the steps of:
- placing the liquid sample in a holder having a partition, the partition being impermeable to vapor from the liquid sample and permeable to alpha particles from the liquid sample;
- and
- using a detector to measure the alpha particle emission level of the liquid sample.
A sample holder for use with an alpha particle detector, the sample holder comprising:
- a base that defines a tub for receiving a liquid sample, the base being sized for receipt in the alpha particle detector;
- and
- a partition located between the tub and the alpha particle detector, the partition being impermeable to vapor from the liquid sample in the tub and permeable to alpha particles from the liquid sample in the tub.
