Embodiment Construction
[0031] A method for quickly investigating and evaluating the radioactive radiation environment in a coal field described in the present invention will be further described in conjunction with specific examples below.
[0032] Use multi-channel gamma energy spectrometers on the ground or in drilling with qualified instrument performance to measure the nuclide content of uranium, thorium, and potassium in the coal field; convert the uranium, thorium, and potassium nuclide content in the coal field according to the conversion coefficient of the radionuclide content and the activity concentration unit on site. Potassium activity concentration; on-site calculation of gamma radiation dose rate based on the activity concentration of uranium, thorium, and potassium in the coal field; on-site estimation of the effective dose equivalent of gamma radiation to residents in the coal field environment based on the gamma radiation dose rate; finally, the coal field is completed with the above ...
