Now, I received a survey meter visited the other day.
Heading images, heading right, Victren ＃CDV700 1973-image left, Victren ＃CDV715 1976-desire ~ ~ ~ ~'s including vintage, but correction stamp press once in 10 years. This is when ＃CDV715 is not functional, this meter begins to swing when life is in danger.
That is pretty strong dose. ＃CDV700 is 715 has a sensitivity of 1000 times. It can be used once.
100 Companies despite their errors than the survey meter near Yukichi etc can be used.
Below are the specifications for ＃CDV700. Measuring beta and gamma rays: gamma ray comes from cesium-137, iodine-131 out of beta rays.
This means that discover iodine-131 and cesium-137.
-Β-Ray and x-ray mesurement (probe is open): iodine-131 and cesium-137 at the same detection.
-Measuring range: 3-stage set ：0.0-0.5mR/h, 0 - 5mR/h, 0 - 50mR/h
-Measuring range /0.00mR/hr-50mR/hr （ about 0.00 µ SV/h-power / / 435 µ SV/h (microsievert per hour) "d" batteries (not included with ）
• Operating temperature-20 ° c ~ + 50 ° c
-Unit mR/h, scale degrees are 0 01 02 03 04 05 until May.
Showing 0.0 ~ 0.5 If x 10.
1mR/h＝8.7 μ Sv, so minimum scale is 0.01mR/h＝0.087 µ SV/h, minimum ticks can be found in the naked eye is 0.005 mR / h.
Can see with the naked eye because the minimum tick is 0.005mR/h=0.0435 µ SV/h.
Vibrobo home garden. 0. 025mR/h = 0. 2175 µ Sv/hx24hx30dX12m＝1879.2 µ Sv 1879.2 x 1 / 1000 = 1.
HM 8792 mSv, general annual radiation exposure values less now.
Happy, and happy.
