The harm of the high-susceptibility groups such as youngster, baby is huge by its.
With industry, agricultural etc. application radioactive source and material it is local more and more, be a large amount of of medical radiation course by it
Increase so that the risk more and more higher that ruck is radiated.
At present, known Wristwatch type nuclear radiation measurement reminds instrument all to use silicon semiconductor detector or Geiger Muller substantially
Counting tube detector, their sensitivity are low, and response speed is slow, and circuit design is simple, are mainly used in known in the presence of compared with hot
Place, the professional Radial-stricken Workers in Nuclear Industry hand exposure dosage of monitoring is not suitable for the general public and found at one's side to quick
Potential radiation hazradial bundle." Wristwatch type personal dosimeter " and White Russian sieve as disclosed in Chinese utility model patent CN 202837555
This Polimaster PM1208 and PM1603 Wristwatch type gamma dosemeter.
