| Deluxe Wipe Test Counter. |
NRC Requirement "A licensee shall survey for removable contamination, once each week, all areas where radiophamaceuticals are routinely prepared for use, administered or stored." - Nuclear Regulatory Commission Publication 10CFR, "Medical Use of By-Product Material," Paragraph 35.70, "Surveys for Contamination and Ambient Radiation Exposure Rate" Introduction The Deluxe Wipe Test Counter is a rugged, miniaturized system for determining removable radioactive contamination (wipe testing). Though priced much lower than well counters and other types of wipe test counters that produce comparable results, the Deluxe Wipe Test Counter's reliability, accuracy, ease-of-operation and convenience make it the best choice everywhere that wipe testing must be performed. Applications The Deluxe Wipe Test Counter consists of a thin-window (2mg/cm2) Geiger-Mueller tube that detects beta and gamma radiation and a microprocessor that utilizes built-in memory to convert the data to thousands of disintegrations per minute (kDPM), the units in which this data is reported. The instrument counts 0.5 inch diameter wipe samples or cotton swabs. In addition to "pass/fail" indicators--a green light (PASS) for contamination less than the preset threshold, a red light (FAIL) if contamination exceeds the threshold--this deluxe 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 (e.g., iodine and other beta emitters have a maximum allowed contamination level limit of 200 DPM in uncontrolled areas). As an added convenience, the instrument can also be used as a scaler, displaying counts to three or four significant |  |
| figures up to a maximum of 999 x 106. The counting times available are 1, 5 and 20 minutes. The Deluxe Wipe Test Counter includes a Here's how easy it is to meet the NRC requirements using the Deluxe Wipe Test Counter... Step 1 Press the Background button. This initiates a background count which takes about 20 minutes. When the background light goes off, the count has been completed. This needs to be done only once before the first sample in a group. Step 2 Place the test source in the sample tray and press the Calibration or Test button. At the end of one minute, the light will go off and the instrument will be calibrated. Step 3 Place a wipe test sample in the holder and press the Count button. At the end of the count period, there will be a green or red "signal" light. The green light indicates "pass" (less than 2000 DPM). The red light indicates "fail" (2000 DPM or higher).

| Cal/Rad Wiper Multi-Channel Analyzer Single-Well Wipe Test Counter. |
 |
Meets all requirements for nuclear medicine wipe testing. The Wiper is a compact, highly sophisticated, 4096 channel analyzer specifically developed for wipe testing in a nuclear medicine setting. The Wiper satisfies the strictest regulations, while providing a superior user interface, with its single well-type Nal(TI) detector. Sophisticated software makes getting accurate, detailed location reports fast, easy and effective. Up to 20 pre-defined locations may be entered into the system. On a daily or weekly basis, the user simply chooses "Do Wipe Test" from the main menu, selects a location from the library, and counts. A detailed report will be printed to the screen and/or the optional printer. For added versatility, the user may send |
| all isotope data to a computer for storage or to another department via the built-in serial port. Other Special Features: SPECIFICATIONS: Detector: Well-type Nal(TI) integral line single-piece assembly Shielding: .75" (20 mm) virgin lead Analyzer: 4096-channel MCA Well Liner: Removable, inert plastic Display: Backlit LCD; 4.5-inch (11.25 cm) diagonal Data Output: Via screen, serial port, full or compact printer Data Input: Alphanumerical keypad Power: 110/220 VAC; .5/.25 Amp; 50/60 Hz; 30 Watt Dimensions: Base Unit: 10.5' wide x 8.5" deep x 10" high (27 cm x 22 cm x 25 cm). Detector: 6" diam. x 10" high (15 cm x 25 cm) Weight: 32 lbs (14.5 kg) |  |

Introduction The time spent counting wipes represents a waste with respect to income generation by the department. Therefore, it only stands to reason that the larger the department, the greater the need for high throughput wipe test counting. The small extra cost of a multi-well counter pays for itself within a short time as a result of enormous time savings and throughput. Utilizing the same, highly sensitive Nal(TI) well-type detectors as the Wiper™, the Genesys 5000 remains highly efficient across the energy spectrum. Applications The Genesys 5000™ series of multi-well gamma counters is ideal for the larger or higher volume department which can't waste all day counting a large number of wipes on a single well counter. Choose from 5, 10, 15, 20 or 25 wells to match your volume needs. Imagine the time saved by counting up to 25 wipes simultaneously. A unique single analyzer optimized with anti-coincidence circuitry borrowed from gamma camera technology makes certain that all samples are treated identically for maximum accuracy. DPM calculations, full-page printout and easy interfacing to a computer for long-term storage of data is simple and |
| efficiently accomplished. Designed to meet or exceed all NRC and State regulations, the Genesys 5000 series combines speed, efficiency and accuracy in a cost-conscious package for the larger department.
