US Patent:

20190017917, Jan 17, 2019

Filed:

Jun 27, 2018

Appl. No.:

16/020774

Inventors:

- Red Bank NJ, US
John Mauro - Red Bank NJ, US

Assignee:

Mauro & Associates, LLC - Red Bank NJ

International Classification:

G01N 15/06
G01N 15/02

Abstract:

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 an airborne dust concentration and a first distribution of aerodynamic diameters of particulates in air passing the prefilter, the particulates including depleted uranium particulates. The monitor further includes a sample filter web that collects the particulates; a solid state detector that detects alpha radiation emitted by the collected particulates; a processor that executes machine instructions embodied on a non-transient computer-readable storage medium to compute a dust loading on the sample filter web; and the processor computes an indication of alpha concentration detected by the detector mechanism.
