RAM905a Iodine 125 particle source special activity meter

RAM905a Iodine 125 particle source special activity meter

Product introduction

The 125I particle source special activity meter is a precision measuring instrument specially used to measure the activity of implanted 125I particle sources. It uses a 4πr high-pressure sealed well-type ionization chamber. It is simple to operate, fast and accurate in measurement, and meets GB/T 10256-2013, JJG 377-1998 national standards and verification regulations.

Features

• Can measure 125I solid internal irradiation radioactive particle source;
• Equipped with a special nuclide measurement container to accurately position the measured nuclide in the ionization chamber and reduce measurement errors;
• Press the button to automatically deduct the environmental radiation background, no need to adjust to zero;
• Place the sample and automatically perform measurement and range conversion. You can also manually switch the Ci/Bq unit display for fast and accurate measurement;
• Keyboard modification and solidification nuclide scale coefficient, no need to develop tools;
• The nuclide activity measurement report can be printed out;
• An optional remote computer can take over the functional operation of the activity meter on the Chinese Windows platform, and you can set the serial port address, scanning rate, data storage rate and panel nuclide name by yourself.
