Introduction

General Description

Section 1

Introduction

1.1 General Description

The Model 6000-528 External Ion Chamber is a low profile ion chamber designed to measure diagnostic x-rays from 30 to 150 kVp. The external ion chamber consists of an ionization chamber and a 15-foot cable assembly.

1.2 Application

The Model 6000-528 External Ion Chamber is specifically designed to be used with the NERO® 6000B, 6000M, 4000+, or the 4000M+ for measuring exposure from diagnostic x-ray machines. It can also be used with any properly configured charge measuring electrometer. The coaxial BNC on the chamber body is the signal output. The recessed banana plug is the high voltage connection for chamber bias. The middle hole is threaded with a standard 1/4 - 20 thread for accessory mounting.

1.4 Procedures, Warnings and Cautions

The equipment described in this manual is intended to be used for the detection and measurement of ionizing radiation. It should be used only by persons who have been trained in the proper interpretation of its readings and the appropriate safety procedures to be followed in the presence of radiation.

Although the equipment described in this manual is designed and manufactured in compliance with all applicable safety standards, certain hazards are inherent in the use of electronic and radiometric equipment.

Warnings and Cautions are presented throughout this document to alert the user to potentially hazardous situations. A Warning is a precautionary message preceding an operation that has the potential to cause personal injury or death. A Caution is a precautionary message preceding an operation that has the potential to cause permanent damage to the equipment and/or loss of data. Failure to comply with Warnings and Cautions is at the user's own risk and is sufficient cause to terminate the warranty agreement between Fluke Biomedical, Radiation Management Services and the customer.

Adequate warnings are included in this manual and on the product itself to cover hazards that may be encountered in normal use and servicing of this equipment. No other procedures are warranted by Fluke Biomedical. It shall be the owner's or user's responsibility to see to it that the procedures described here are meticulously followed, and especially that Warnings and Cautions are heeded. Failure on the part of the owner or user in any way to follow the prescribed procedures shall absolve Fluke Biomedical and its agents from any resulting liability.

Indicated battery and other operational tests must be performed prior to each use to assure that the instrument is functioning properly. If applicable, failure to conduct periodic performance tests in accordance with ANSI N323-1978 (R1983) Radiation Protection Instrumentation Test and Calibration, paragraphs 4.6 and 5.4, and to keep records thereof in accordance with paragraph 4.5 of the same standard, could result in erroneous readings or potential danger. ANSI N323-1978 becomes, by this reference, a part of this operating procedure.
