Ion Chamber Survey Meter with Beta Slide

harpell — Thu, 10 Dec 2009 01:08:51 +0000

The auto-ranging 451B measures radiation rate and accumulated dose from beta, gamma and x-ray radiation sources. The 451B’s site surveying capabilities make it well-suited for a wide range of end users, including: police and fire departments, x-ray manufacturers, government agencies, state inspectors, emergency response and HAZMAT teams, nuclear medicine labs, hospital radiation safety officers, and nuclear power workers. The ion chamber detector allows for a fast response time to radiation from leakage, scatter beams and pinholes. Additionally, the
*low noise chamber bias supply provides for fast background settling time. A sliding beta shield serves as an equilibrium thickness for photon measurements and enables beta discrimination. The digital display features an analog bar graph, 2.5 digit digital readout, low battery and freeze (“peak hold”) mode indicators, and an automatic backlight function. User controls consist of an ON/OFF button and a MODE button. The case is constructed of lightweight, high strength materials and is sealed against moisture. The RS-232 interface can be connected directly to a computer for use with the Excel add-in for Windows® (451EXL), enhancing the functionality of the instrument. This software allows for data retrieval, ser parameter selection and provides a virtual instrument display with audible (requires sound card) and visual alarm indication.

The 440RF/D is a highly sensitive, low energy, RF shielded survey meter suited for fast, accurate measurements of background and other low radiation levels. In particular, the 440RF/D is used to measure radiation exposure in the color television industry (cathode-ray tube leakage), radar and transmission towers where RF may be present, and surveying applications in high RF fields. Approved by the Electronic Industries Alliance, the 440RF/D is designed to meet the radiation sensitivity and measurement requirements for television receivers set forth by the US Department of Health and Human Services. Entitled “Performance Standard for Televisions Receivers” (21 CFR 1020.10), this standard requires that “radiation exposure rates produced by a television receiver shall not exceed 0.5 milliroentgens per hour at a distance of five centimeters from any point on the external surface of the receiver.”

Designed for use in conjunction with the ASM-990 Series and other standard GM survey meters, the 489-110D can detect alpha, beta, and gamma radiation. It is configured for operating convenience in table-top and floor surveys as well as surveys of personnel and equipment. Prime applications for this probe include nuclear medicine counter tops and frisker stations, leakage detection for low energy diagnostic x-ray machines, geological and environmental surveys or any place where there exists the suspicion that some form of radiation is present, especially emergency response teams. For storage and carrying ease, the probe fits into the standard handle clip on a survey meter.
The GM probe comes in two configurations: 489-110D with an ABS plastic housing, MHV connector, and foam grip, or 489-110E with a BNC connector. This selection of connectors provides the ability to attach the GM probe to most GM survey meters on the market. Replacement foam grip handles are available: 489-130-44. This same probe design is available in a rugged metal housing as 489-110C.

Energy Compensated GM Probe

harpell — Thu, 10 Dec 2009 01:08:51 +0000

The Model 90-12 is a rugged, lightweight, energy compensated, general-purpose Geiger-Mueller (GM) tube based hand held probe, with beta shields. This probe is designed to fulfill a variety of radiation measurement needs. The adjustable beta shield is a 360º shield with a linear movement to permit is crimination between penetrating and non-penetrating radiation. The two windows expose an angle of 180º total in the most sensitive area of the GM tube. With the shield open, the probes measure beta, x-rays, and gamma rays. With the beta shield closed, the probes measure penetrating x-rays and gamma rays. A coiled coaxial cable connects these probes to a wide variety of Fluke Biomedical survey meters. The energy compensation feature permits accurate exposure rate measurements from low to high energies, at rates less than 1 R/hr.

Features:

Energy compensated GM probe provides flat energy response for reduced GM tube over-response at low energy dose rates
Beta shield discriminates between beta rays and gamma/x-ray radiation
360º beta shield
2 beta windows expose 180º for optimum sweet spot
Rugged ABS plastic housing
