Performance introduction: the one-10 road independent sampling device of the win-8a-type 1-10 road can be individually measured and separately produced by each channel. When the instrument works on any of the incoming sample, it can still place the sample on the other sample drawing board to start the measurement. 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 features:

1. The channels are individually and in a flexible manner, consistent with international counterparts.

2. Independent measurement, non-interference and high efficiency of each channel.

3. Each channel can print the measurement results independently to meet the diversified demand.

4. The program software has the ability to pause and continue to collect functions.

5. The measurement data can be saved automatically to avoid loss of data.

6. Each channel can print the measurement results separately or in combination, and facilitate data consolidation.

7. The instrument has power failure memory function, and the software can prompt the unfinished item and continue to complete the remaining 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 0.15 cm-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 55% 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

The instrument meets the national standard detection limit: alpha: 1.6 x 10-2bq; Beta: 2.8 x 10-2 bq
