Development, the needs to meeting environmental monitoring and scientific research are very important.Electrostatic collection alpha energy spectrum method is to realize radon consistence
The preferred option of continuous measurement, the method have higher detectivity.But the detection efficient of electrostatic emanometer is easily by temperature
The impact of humidity, is to reduce impact of the humiture to its collection efficiency, must add drying tube in air inlet to be dried sampling during measurement
Gas, which palpus Jing often change desiccant, make troubles to long-term continuous measurement.Before sampling drying tube sampling is added to deposit simultaneously
In volume time delay, using the volume time delay for having more than 40 minutes during big drying tube, it is difficult to meet quick measurement change radon dense
The needs of degree.A set of NRL-II types Continuous Instrument for Radon is studied and developed in University Of Nanhua based on static collection, and the emanometer is not
Need using desiccant to be dried gas sampled, but directly using the automatic change corrected to realize ambient temperature and humidity of humiture
Change, it is ensured that ambient temperature and humidity change will not be impacted to the accuracy for surveying radon.To guarantee that the humiture result for measuring accurately may be used
Lean on, thus design a kind of integrated form measurement chamber of emanometer, the device is not only simple in structure, reliable and stable, but also is a kind of
The integrated form measurement chamber for using easy to spread.
Utility model content
The purpose of this utility model is to overcome the problem of prior art presence and provide a kind of simple structure, stably may be used
By, it is easy to spread use integrated form measurement chamber.
This utility model is realized using following proposal：A kind of integrated form measurement chamber of emanometer, including air inlet, son

It is connected with straightway pump, the 3rd tunnel is connected with Temperature and Humidity unit.
The main control unit adopts digital integrated electronic circuit；
The Temperature and Humidity unit adopts high-precision AM2302 Temperature Humidity Sensors.
Operation principle of the present utility model is briefly described as below：Straightway pump is sampled, and makes the air containing radon with certain flow rate (e.g., Q=
3Lmin-1) enter Jing after daughter high efficiency particulate air filter and measure chamber, the radon consistence of intracavity to be measured is reached with the radon consistence of test environment
During balance, open high-pressure modular and sufficiently strong electrostatic field is formed between the locular wall and semiconductor detector in measurement chamber, will measurement
A part of positively charged that the decay of intracavity radon is produced218Po particle collections are on semiconductor detector surface, real in its natural state
It is now right218The alpha-particle of the 6.00MeV that Po is produced carries out effectively reliable power spectrum and screens, and drastically increases the sensitive of radon measurement
Degree.This utility model, is automatically controlled with digital circuit, Temperature and Humidity unit is integrally formed with measurement chamber, greatly
Improve the reliability of measurement apparatus.In sum：This utility model has simple structure, reliable and stable, easy to spread makes
The advantages of using.
