Description

Technical Field

[0001] The present invention relates to the technical field of surface contamination monitors, in particular to a remotely controlled surface contamination monitor. Background Art

[0002] Contamination is a potential risk wherever radioactive materials are used. Portable contamination monitors measure surface contamination using large-area probes. The pulses detected by the probe and electronic circuitry are displayed as measured values and audible pulses. The CoMo contamination monitor utilizes new microcontroller technology, displaying all measurement data and information on an LCD. The plain text display makes it easy for even those new to contamination monitor operation to quickly learn how to use it.

[0003] In areas with radiation, workers may be contaminated by radioactive sources in the environment while working. After entering and leaving the contaminated area, a test should be conducted to determine whether the workers have been contaminated by the radioactive environment.

This is not only time-consuming and labor-intensive, but also increases the risk of radiation exposure. Summary of the Invention
