Problems solved by technology

The traditional accumulative activated carbon adsorption radon measurement method requires the sampler equipped with activated carbon to be buried underground for several days or even tens of days. The survey period is long, the work efficiency is relatively low, and the survey funds required are also large
In the actual exploration of uranium resources, sometimes in order to quickly provide the spatial distribution informatio...

Abstract

The invention relates to a transitory activated carbon adsorption radon sampling device and a method for exploring transitory activated carbon adsorption radon. The transitory activated carbon adsorption radon sampling device comprises a soil gas collector, an electric time suction pump and an activated carbon absorber, wherein the air inlet of the electric time suction pump is connected with an air outlet hole of the soil gas collector, and the air outlet of the electric time suction pump is connected with a duct of the air inlet of the activated carbon absorber. The method for exploring transitory activated carbon adsorption radon comprises that: measurement is carried out three days after on-site data acquisition so as to avoid the influence of thoron effectively; and a multi-fractal spatial interpolation is adopted to achieve excellent effect in maintaining and enhancing local abnormal information and contribute to the highlight of local weal abnormal information on blind uranium mineralization. The device can quickly collect free radon in soil and acquire the abnormal information on radon from a deep area, and contributes to the prediction and evaluation of a blind uranium resource.

Description

technical field [0001] The invention belongs to the field of uranium resource exploration, and in particular relates to an instantaneous active carbon adsorption radon sampling device and an exploration method suitable for uranium resource exploration. Background technique [0002] In the exploration of uranium resources, the activated carbon adsorption radon measurement method is an effective method for locating deep uranium ore bodies. The radon measurement value obtained by this measurement method has a high signal-to-noise ratio, which is beneficial to capture radon from deep concealed uranium ore bodies exception information. The traditional accumulative activated carbon adsorption radon measurement method requires the sampler equipped with activated carbon to be buried in the ground for several days or even tens of days. In the actual exploration of uranium resources, sometimes in order to quickly provide the spatial distribution information of the radon anomaly field...
