Low background alpha beta meter

Performance introduction: win-8a type low background alpha-beta measuring instrument has the following four specifications: one, two, four or six, and one, two, four or six samples can be measured at the same time. All parameters of the instrument are automatically set by software program, and the measurement process is highly automated. The test cost is low, the operation is simple, and the test unit is the first choice to measure the total alpha beta ratio of the sample.

 

Product use: WIN - 8 type a low background alpha beta measuring instrument used for detecting radiation detection, radiation environmental monitoring, nuclear power plant for domestic and drinking water, geological exploration, institutions of higher learning, the entry-exit inspection and quarantine, the third party testing and research institutions in areas such as total alpha, beta, activity of sample concentration measurement.

 

Technical parameters:

I. instrument background

The count rate of alpha particles per unit area is less than 0.003 cm-2min-1;

The counting rate of the beta particles in the unit area is less than 0.1cm-2min-1;

Detection efficiency

Instrument for 239 pu alpha source (active area Φ 25 mm) of two PI detection efficiency more than 85% or higher;

Instrument for 90 sr - 90 y beta source (20 mm) active area Φ 2 PI detection efficiency more than 58% or higher;

3. Repeatability

Repeatability: the instrument continuously measures 24 hours, the detection efficiency changes alpha < 2% and beta < 3%;

Iv. Crosstalk ratio

Alpha entry to beta is less than 1% (to 239Pu),

The number of beta enters alpha channel is less than < 0.3% (for 90sr-90y);

5. Instrument sensitivity

Instrument sensitivity: alpha is greater than 5 x 10-5bq; Beta 1 x 10-6 or higher bq

measurement

1) you can measure alpha beta at the same time, or alpha beta or beta separately;

2) the measurement process and measurement results can be displayed on the display and can be printed.

3) measurement time, alpha threshold of the detector, beta low threshold (beta L), beta high threshold (beta H) and high pressure can be adjusted by computer according to the requirements.

7. Data processing: the software of instrument supporting program operating system, automatic measurement.

Working conditions

1) power supply voltage: ac 220V plus or minus 10%; 50 hz.

2) ambient temperature: 5 ~ 400C plus or minus 20C;

3) relative humidity: < 90% (+ 300C).
