I ALERT便携式多功能辐射检测仪是一款便携式辐射检测仪，可监测低剂量的α射线、β射线、γ射线和X射线, 此辐射检测仪可检测和测量表面放射性玷污以及核辐射后的二次辐射。也可作为监测原子核工作环境如反应堆,核电厂,X-射线机周围可能存在的核辐射泄漏和强度的辐射巡测仪使用。
I ALERT便携式多功能辐射检测仪可检测惰性气体（如氡）及其他物质如建筑石材，进口废钢等的放射性辐射强度。是申请企业辐射安全许可证必备仪器。

常用于：

1.检查局部的辐射泄露和核辐射污染；

2.检查石材等建筑材料的放射性；

3.检查有核辐射危险的填埋地和垃圾场；

4.检测从医用到工业用的X射线仪器的X射线辐射强度；

5.检查地下水镭污染；

6.检查地下钻管和设备的放射性；

7.监视核反应堆周围空气和水质的污染；

Handheld Surface Contamination Meter

The Inspector Alert measures alpha, beta, gamma and x-radiation using a 2-inch pancake GM detector with high sensitivity to common beta and alpha sources.

The easy-to-read digital display shows readings in your choice of mR/hr, CPM, CPS, or μS/hr. The Total/Timer feature allows timed readings from one minute to 24 hours for precise measurement of low level contamination. An audible alert sounds when the radiaiton reaches a user-adjustable level.

1.Quickly alerts first responders to the presence of harmful levels of nuclear radiation

2.Improves safety in the laboratory and in the field

3.Automatically compensates for GM tube dead time

4.Will not jam in high radiation fields

5.Meets CE certification requirements for Europe
