Digital Contamination Monitor (DIGICON)

Introduction

In many applications of radiation in medicine and industry, the working areas have to be monitored routinely in order to minimize radiation exposures to workers and also public in general. This is called area monitoring and the instruments used to determine the radiation levels are called area monitors. The radiation levels to be measured in area monitoring are from very low levels to very high levels. These area monitors should have suitable indicators to display the radiation levels. While working with unsealed radioactive sources in open isotope laboratories, hospitals and nuclear medicine centers, any spillage of radioactive materials either in powder or liquid form on work tables, floorings etc. is called contamination. This contamination can cause radiation hazard through intake or inhalation. Contamination monitors with digital display is called DIGICON (Digital Contamination Monitor). GM Counter type IND 72314 is used as a detector. Maximum surface contamination level is 0.3 m rad/hr for b and g radiation and it is required that contamination monitors available should be able to measure at least one tenth of this value. 

Specifications

Application Areas

DIGICON (Digital Contamination Monitor) is used to measure contamination levels due to radioactive materials emitting beta and gamma radiations in open isotope laboratories, hospitals and nuclear medicine centers.
