產(chǎn)品詳細(xì)介紹I ALERT便攜式多功能輻射檢測儀是一款便攜式輻射檢測儀，可監(jiān)測低劑量的α射線、β射線、γ射線和X射線, 此輻射檢測儀可檢測和測量表面放射性玷污以及核輻射后的二次輻射。也可作為監(jiān)測原子核工作環(huán)境如反應(yīng)堆,核電廠,X-射線機(jī)周圍可能存在的核輻射泄漏和強(qiáng)度的輻射巡測儀使用。
I ALERT便攜式多功能輻射檢測儀可檢測惰性氣體（如氡）及其他物質(zhì)如建筑石材，進(jìn)口廢鋼等的放射性輻射強(qiáng)度。是申請企業(yè)輻射安全許可證必備儀器。
常用于：
1.檢查局部的輻射泄露和核輻射污染；
2.檢查石材等建筑材料的放射性；
3.檢查有核輻射危險(xiǎn)的填埋地和垃圾場；
4.檢測從醫(yī)用到工業(yè)用的X射線儀器的X射線輻射強(qiáng)度；
5.檢查地下水鐳污染；
6.檢查地下鉆管和設(shè)備的放射性；
7.監(jiān)視核反應(yīng)堆周圍空氣和水質(zhì)的污染；
8.檢查個(gè)人的貴重財(cái)產(chǎn)和珠寶的有害輻射；
9.檢查瓷器餐具玻璃杯等的放射性；
10.精確定位輻射源；
11.家居裝飾的檢測。

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
