INSPECTOR ALERT便攜式多功能射線檢測儀
INSPECTOR ALERT便攜式多功能射線檢測儀是一種健康、安全的儀器,被廣泛應(yīng)用于檢測低強度輻射。其應(yīng)用范圍如下:
- 探測和測量表面沾污
- 在操作放射性核素時監(jiān)測可能存在的放射性暴露量
- 調(diào)查環(huán)境污染
- 測定惰性氣體及其它低能放射性核素
- 建筑裝飾材料表面放射測定
該運用蓋革計數(shù)管來來測定α、β、γ及Χ射線輻射。每次射線穿過管子并引起電離時,蓋革計數(shù)管會產(chǎn)生一脈沖電流。每個脈沖都是電子探測并進(jìn)行運算。探測器以你選擇的模式顯示計算:CPM,mR/hr,或者總計。在s1單位中,使用CPS和μsv/hr。檢測器探測出來的計數(shù)數(shù)字由于放射能的任意狀態(tài)而每分鐘都在變化。以過去一段時間內(nèi)的平均值表示更加準(zhǔn)確,而且這段時間越長數(shù)據(jù)越準(zhǔn)確。
簡 介:
INSPECTOR ALERT便攜式可以測定α、β、γ和x射線。用來探測輻射強度的微小變化,并且對通常的放射性核有很高的靈敏度。
檢測器計數(shù)電離情況并將結(jié)果顯示在液晶顯示器(LCD)上。該檢測器設(shè)計為既可以使用常規(guī)的單位(mR/hr 和CPM),又可以使用s1單位(μsv/hr和CPS)。使用模式開關(guān)可以顯示你所選擇的測定單位。
檢測器運行時,每探測到一次計數(shù)(一個電離過程),紅計數(shù)燈就會閃動一次。
mR/hr μsv/hr.數(shù)字顯示器顯示輻射強度可以從.001到100. mR/hr。用s1單位時,顯示出當(dāng)前輻射程度可從.01到1000μsv/hr.
CPM CPS.以每分鐘計數(shù)時,顯示器顯示出的當(dāng)前輻射強度可從0到300,000CPM。在顯示×1000時,用1000乘所讀的數(shù)字即為zui終數(shù)據(jù)。在使用s1單位時,顯示器顯示的輻射程度以每秒計數(shù),可從0到5000CPS。
Total/Timer 開關(guān)至于這個位置時,顯示器顯示從開關(guān)置于這一位置開始計數(shù),累積計數(shù)總量可從0到9,999,000。在顯示×1000時,1000乘所讀數(shù)字即為zui終獲得的數(shù)據(jù)。

The Inspector Alert
Handheld Surface Contamination Monitor
The Inspector 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 m Sv/hr. The Inspector automatically compensates for GM tube dead time. Anti-saturation circuitry prevents jamming in high radiation fields. The Inspector meets CE certification requirements for Europe. | |
The Total/Timer feature takes timed readings for periods from one minute to 24 hours for precise measurement of low-level contamination. Our "safety first" calibration feature can eliminate radiation exposure to the calibration technician. |

Display: 4-digit liquid crystal display with mode indicators Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases. User can select fast 3-second averaging period. Operating Range: mR/hr: .001 to 100.0; CPM: 0 to 300,000; Total: 1 to 9,999,000 counts; mSv/hr: .01 to 1,000; CPS: 0 to 5,000 Efficiency: Sr-90 (546KeV, 2.3MeV b max): approx. 75%; C-14 (156KeV b max): approx. 11%; Bi-210 (1.2 MeV b max): approx. 64%; Am-241 (5.5 MeV a): approx. 36% Sensitivity: 3500 CPM/mR/hr referenced to Cs-137 Accuracy: 15% Timer: Can set 1-10 minute sampling periods in 1-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour increments Count Light: Red LED flashes with each radiation event Audio: Beeper beeps with each radiation event; can be muted Outputs: Dual miniature jack drives CMOS or TTL devices, sending counts to computer or data logger. Submini jack allows for electronic calibration.
