Basic Knowledge of Radon Detectors

Basic Measurement Knowledge - Radioactive Activity, Wholesale of GB50325 Portable Radon Detectors, Radon Activity Concentration 1) Radioactive activity refers to the number of radioactive decays per unit time, measured in Bq (Becquerel). Previously, the Curie (Ci) was used to express the unit of radioactive activity, which is now obsolete. The conversion relationship is: 1Bq = 0.27 × 10^-6 Ci. 2) Unit of Radon Activity Concentration: The activity of radon in a unit volume is called the radon activity concentration. Since radon gas is a "rare gas" and occupies a very small proportion in the atmosphere, it is difficult to express in weight, so we do not mention "radon concentration" but "radon activity concentration." 1Bq/m³ indicates the presence of 1Bq of radon gas in one cubic meter of air. 3) The commonly used conversion relationship is: 1Bq/L = 1000Bq/m³.

How many categories of radon meters are there?

Radon, the elemental form of radon, is a colorless, odorless, tasteless inert gas with radioactivity. Its presence can pose health hazards to people in their living and working environments. Survey results indicate... Firstly, the methods and principles for detecting radon concentration in soil are introduced.

Radon Detector

This instrument is used for detecting the chemical element radon. The data measured by the radon meter includes radioactive activity and radon activity concentration. Radon typically exists in its elemental form as radon gas, which is colorless, odorless, and tasteless, and is an inert radioactive gas. Radon is not very reactive chemically, and it is also difficult for radon to react with other elements to form compounds.

Radon Detector Introduction

Three natural radioactive series exist in nature, namely the uranium-lead series (starting element 238U), the actinium-uranium series (starting element 235U), and the thorium series (starting element 232Th). Radon (222Rn) and its isotopes 219Rn and 220Rn are the only gaseous radioactive elements among these three natural radioactive series. 235U is always found alongside 238U, and portable radon detectors are in bulk supply, while 232Th coexists with 238U under certain conditions. 238U is widely present in the Earth's crust, meaning radon is ubiquitous; its concentration just varies.
