Product Description
RDA-150 α β surface is pollution
RDA-150 type α β surface pollution instrument is mainly used for measuring the object surface alpha β radioactive pollution level surface, can also be measuring γ radiation dose rate, low levels of radiation was very sensitive. On the wall of pollution, desktop, floor and staff of the body parts and working clothes, α β pollution has good measure characteristics. Used in nuclear power use each of the mines, workshop, laboratories, decommissioning nuclear facilities, nuclear power plant, nuclear military and nuclear protection department, etc. Can be used as should nuclear urgent measure box equipment. With large area, high sensitive, multi-function, easy operating characteristics.
Instrument measurement reading with backlit by dot matrix LCD given, to alpha and beta, γ measurement can switch over the show, by the handle when measuring the key operate, and Settings manually reset counter and automatic reset count two working way, convenient use, easy to control.
Has the alarm threshold, the alarm, battery voltage range alarm functions.
▲ α β surface pollution index is technology
1. The probe: large area semiconductor detector and high sensitivity GM detector;
2. Measuring range: alpha count rate: 1 ~ 2000 CPS; β count rate: 1 ~ 5000 CPS; Alpha, beta, but shows at the same time. Environmental γ dose H * (10) measurement range: 0.1 mGy/H ~ 12 mGy/H;
2. For the surface to sensitive window minimum distance: 4.2 mm;
3. For the surface to sensitive volume equivalent quality thickness: < 1.6 mg/cm2;
4. Probe protective cover: storage and transportation ChuangMo protect probe. Because with a corresponding shielding materials, which can effectively block alpha, beta rays, and measure of gamma good energy response compensation. The beta/gamma rays mixed field, to 90 Sr-90 Y β ray keep out rate is 97%; And in the 241 45 cm place Am source, gamma rays through rate of 70%.
5. α this bottom: < 5 CPM;
6. β this bottom: than 400 CPM (external environment of γ radiation < 0.25 mGy/h);
7. α detection efficiency: 35% quartile (241 Am 239 or Pu, 2 π direction, away from Windows 150 cm2 source surface 4.2 mm);
8. β detection efficiency: 60% quartile (204 or 90 Tl Sr-90 Y, 2 π direction, 150 cm2 source);
40% quartile (14 C, 2 π direction, 150 cm2 source);
9. Relative intrinsic error: than-20%;
10. Timing: have 1 s, 10 s, 60 s, ∞ four file;
11. The work environment characteristics: temperature 0 ℃ ~ 45 ℃;
12. Weight: 1.6 kg; Size: (long) 22.5 cm... (wide) 11.8 cm... (high) 16.3 cm (including the handle).
