Ludlum Model 3030P

Alpha/Beta Radiation Sample Counter

Introduction

Ludlum Model 3030P Alpha Beta Radiation Sample Counter ● Fully Integrated Alpha/Beta Radiation Sample Counter

● Simultaneous Alpha and Beta Counting

● Employs PIPS™ Solid State Detector

● Ultra Low Alpha/Beta Crossover and Backgrounds

● Adjustable Alpha Window for Radon Rejection

● Data Logging with USB Connectivity

● 48-Hour Battery Operation

● Includes PC Software

The Ludlum Model 3030P’s solid state PIPS^TM detector facilitates efficient and cost-effective simultaneous alpha and beta radiation sample counting for air filters, smears and swipes. This instrument meets the newer Electric Power Research Institute (EPRI) guideline for detecting a few DPM of alpha amidst a several hundred thousand DPM beta background. All data are automatically logged and easily retrievable via a USB connection. The light weight and battery operability afford convenient use out in the field. With the optional detector shield, the Model 3030P can be used virtually anywhere. The instrument comes with a PC Control Software that allows the user to set all parameters, view QC check settings, change alpha and beta window and threshold values, perform MDA (Minimum Detectable Activity), and retrieve the sample data saved to the logging memory.
