The Radon meter tells you how radon gas enters the interior of the house.
What is Radon?
Radon, although colorless, odorless, and tasteless, is an inert gas with radioactivity. When inhaled, the alpha particles emitted during radon decay can cause radiation damage to the human respiratory system and trigger diseases. Building materials, such as granite, brick sand, cement, and gypsum, are the primary sources of indoor radon, especially natural stones containing radioactive elements. The material surface can release radon, particularly with the FD218 process. Therefore, it is necessary to use a radon meter to measure indoor radon levels to prevent the occurrence of related diseases.
TwoWhat is the principle of radon measurement?
By using a sampling pump or free diffusion method, radon from the air to be tested is drawn into or diffused into the measurement chamber. The concentration of radon in the air to be tested is calculated by measuring the α-radioactivity of the daughter products produced by the collected radon or the daughter products concentrated by electrostatic adsorption.
Three: What are the general steps for radon meter detection?
To assess indoor radon levels, a two-step measurement process is employed: 1. Screening measurement, used to quickly determine if the building poses a potential high radiation risk to its occupants. 2. Tracking measurement, used to estimate the health risk to occupants and to evaluate the effectiveness of quality control measures.

Radon Measurement Instrument Overview
The Radon and its Daughter Continuous Monitor is a portable, "real-time" and "continuous" measurement instrument for radon concentration and radon daughter to total potential alpha concentration. FD218 wholesale for radon emission from material surfaces, featuring an "active" sampling structure, is typical for underground engineering, mine shafts, tourist caves, nuclear facilities, associated uranium mines, and indoor radon measurement, health supervision, and radioactive detection evaluation. It is an essential device for identifying radon (thorium) sources, radon management, and radiation safety assessment, and meets the application research requirements of the Radiation Effects Association for radon daughter monitoring and radon dose estimation. It provides immediate results, is easy to operate, convenient to carry, and suitable for large-scale radon level surveys.
