LSPEC 160 radon meter

LSPEC 160 radon measuring instrument is a continuous radon measuring instrument, which uses static electricity to collect radon decay daughters for cumulative measurement. It has high sensitivity, small volume and convenient operation to obtain results on site. It can be used for indoor radon measurement, radon measurement in soil, radon measurement in aqueous solution and other fields.

LSPEC 160 radon meter is a new type of radon measuring instrument that can continuously measure radon. It uses static electricity to collect radon decay daughters for cumulative measurement, with high sensitivity, small volume and convenient operation. It can be used for indoor radon measurement, radon measurement in soil, radon measurement in aqueous solution and other fields.

System configuration:

1. One radon and thorium analyzer host;

2. 1 portable instrument box;

3. 1 power adapter;

4. 1 data connection line;

5. 1 set of data analysis and storage equipment;

6. Two 5m long terminal blocks.

Using semiconductor α Particle detector, by detecting each α The energy of particles to identify the α Particles can be clearly displayed α Spectrum. The sampling chamber is 1.2L, the inner surface is conductive, and the top center is a α For particle detector, positive high pressure is added between the conductive layer and the detector, and an electric field is formed in the internal space to push positively charged particles towards the detector. After the decay of radon - 222, polonium-218 with positive charge is formed, which adheres to the detector under the action of internal electric field. When Polonium-218 with a half-life of 3.05 minutes decays on the detector surface, its α The particles enter the detector and form α An electrical signal that is proportional to the energy of a particle. Different isotope formation α The energy of particles is different, resulting in different intensity spectrum peaks.
