background: radon and its daughter product are a major source of natural radiation exposure, the measurement of radon concentration in dwellings is assuming ever increasing importance. it is known from recent surveys in many countries that radon and its progeny contributes significantly to total inhalation dose and is well established that radon when inhaled in large quantity causes lung disord...

The study concerns the analysis of 220Rn (thoron) recorded in surface soil two sites Campi Flegrei caldera (Naples, Southern Italy) characterized by phases volcanic unrest seven-year period 1 July 2011–31 December 2017. Thoron comes only from most layer, so characteristics its time series are strictly connected to shallow phenomena, which can also act at a distance measuring point these particu...

A survey of inhabitant exposures arising from the inhalation of 222Rn and 220Rn progeny, and lung cancer mortality has been carried out in two adjacent areas in Guangdong Province, People’s Republic of China, designated as the “high background” and the “control” area. Annual exposure rates are 0.38 working level months (WLM) per year in the high background, and 0.16 WLM/yr in the control area. ...

Bài báo nghiên cứu đặc điểm biến động suất liều bức xạ gamma và nồng độ khí phóng radon (222Rn; 220Rn) theo thời gian tại trạm quan trắc môi trường mỏ đất hiếm Mường Hum. Sử dụng phương pháp thống kê để xử lý số liệu gamma, trắc. Kết quả của giúp điều chỉnh sự thiên ngày đêm giá trị trung bình hàng năm khi tính toán hiệu năm. khảo sát 2021 Hum với Radon, Thoron lần lượt là 1,65 1,97.

Rare event physics demands very detailed background control, high-performance detectors, and custom analysis strategies. Cryogenic calorimeters combine all these ingredients effectively, representing a promising tool for next-generation experiments. CUPID-0 is one of the most advanced examples such technique, having demonstrated its potential with several results obtained limited exposure. In t...
