CONFINE SPACE ENTRY RADON DAUGHTER MONITOR (CSERDM – 0.30 L/min model with an internal battery pack)

The Confine Space Entry Radon Daughter Monitor (CSERDM) is a microprocessor based radiation monitoring system that was developed by Radiation Detection Systems (RDS) for the monitoring of the potential alpha energy concentration (PAEC) and the potential alpha energy exposure (PAEE) of radon daughters in confine spaces.

The PAEC of radon daughters may vary significantly in confined spaces. The CSERDM was designed to warn workers when the PAEC and/or the PAEE would reach a certain programmed ALARM value. Because the CSERDM measures the PAEE of radon daughters during the confined space entry the monitor is also used as the personal dosimeter of radon daughters.

The CSERDM has an internal battery (7.2V NiMH 4000mAh). The unit would run for more than 30 hours with the fully charged internal battery (the recommended charging current is 0.7 A).

The CSERDM continuously monitors and logs data into the microcontroller memory during 10 min monitoring intervals. The data log can be downloaded as text file to the MS Hyperterminal or Putty program and open as MS Excel file.
