 Contamination
 

The Wipe Counter (Model 1051) is a rugged, miniaturized system for determining removable radioactive contamination (wipe testing). Although it is priced much lower than Well Counters, the Wipe Counter produces comparable results. Its low cost combined with reliability, accuracy, ease-of-operation and convenience warrant its use everywhere that wipe testing is performed. The Wipe Counter consists of a thin-window Geiger-Mueller tube that detects beta and gamma radiation

A microprocessor converts the data to thousands of disintegrations per minute (kdpm). The instrument counts 1/2" diameter wipe samples or dry cotton swabs. A green light (PASS) indicates contamination less than the present threshold, a red light (FAIL) indicates contamination hat exceeds the threshold. In addition to PASS/FAIL indicators, this instrument has a 4-digit LED digital display indicating the level of contamination in kdpm. The pass/fail threshold can be adjusted for levels other than 2000 dpm for isotopes such as iodine and other beta emitters which may have a maximum allowed contamination level limit of only 200 dpm in uncontrolled areas. As an added convenience, the instrument can be used as a scaler, displaying counts to three or four significant figures up to a maximum of 999*10⁵. The selectable counting times are 1, 5 and 20 minutes.
Cotton swabs can also be used for taking the wipes.

Applications:
· Isotope Contamination Counting.

Features:
· Exceptional Economy.
· Measures surface contamination levels in areas where radiopharmaceuticals are used.
· Digital LED readout plus PASS/FAIL lights.
· Can be calibrated for most common isotopes.
· Can be used as a scalar displaying counts up to 999*10^5.
