| yes. It detects X Ray. From the description, the sensitivity to Gamma Radiation: 0.1~1 MeV |

| I'm a Chinese customers, why my GMC - 300 in radiation displayed when radiation dose is increased a little bit? When no radiation is also a little to reduce |

| There is a background radiation reading always. |

| Can't rise to the actual radiation? It will increase slowly? |

What do you means by "increase slowly"?
What is your back ground rading minimume to maximume? does it consistent over the time? |

| For example, the actual radiation is 5uSv/h, slowly increased to 5.not once become 5.When there is no radiation, is slowly reduced to background radiation value |

From "5uSv/h, slowly increased to 5.not once become 5." ??
What is the unit on your "increased to 5."? increaded to 5.0uSv/h ?

| Step value is too small, to show 5 uSv/h to slowly growth.the actual radiation is 5uSv/h,Growth of 5uSv/h take a few minutes. |

OK. What is the maximume value you got?
The backgroud reading has no fixed value. It always change within a range. It normally in 0.02uSv/h-0.2uSv/h.
If you got 5uSv/h backgroud,then it is high radiation background. |

| Battery problem? You can change to a good 9V rechageable battery. The battery is NiMH 9V with 8.4V norminal voltage. |
