LUDLUM 2401-P is a high-performance pocket radiation meter designed for low-level radiation detection and widely used in nuclear medicine,radiology and industrial environment monitoring.The following is a comprehensive analysis of its core functions and technical features:
I.Core functions and positioning
Multifunctional radiation detection
Supports comprehensive detection ofα,β,andγrays,suitable forβsurface contamination measurement and low-dose radiation environment monitoring,especially for locating lost or displaced radiotherapy seeds(such as radioisotopes).
High sensitivity and response speed
The sensitivity is up to 3300 times/MR/hour(based on cesium-137 gamma rays),and can detect radiation levels as low as 0.15 mR/h.
Short response time,usually only 11 seconds from 10%to 90%final value reading.
Compact and portable design
The size is 1.8×3.3×5.3 inches(4.6×8.4×13.5 cm),weighs only 0.9 pounds(0.4 kg),and has a built-in 2.3 square inch GM detector,which is easy to carry and operate on site.
II.Technical parameters
Detector type:Mica window pancake type GM detector(15 square centimeters effective area).
Measuring range:0-15 mR/h(radiation exposure rate)or 0-50k CPM(count rate).
Power supply:9V alkaline battery,battery life is about 250 hours.
Protection certification:CE certified,in line with industrial safety standards.
III.Application scenarios
Medical field
Locate lost radioactive treatment seeds in nuclear medicine departments to ensure patient safety and treatment accuracy.
