RMD RadCam

Category: Characterization > Monitors > Radiation Monitors
Reference # : Model No :

The RMD RadCam™ produces images of gamma radiation superimposed over a black and white video image of the same field of view. The intensity of the gamma radiation is presented in color with progressively brighter colors corresponding to higher gamma activity. In addition, spectra showing the isotopes present are shown for user-selected areas of the image. The pin-hole collimator, the coded aperture collimator, and user-set data acquisition time give the system a wide range of sensitivity to gamma radiation. The RMD RadCam™ detects gamma radiation and shows the location of radioactivity and a spectrum of the detected gamma photons. This spectroscopic feature helps the user identify the presence of gamma-emitting isotopes such as 241Am, 57Co, 99mTc, 235U, 239Pu, 131I, 137Cs and 60Co. The mask, anti-mask position of the coded-aperture collimator enhances nuclear image quality by reducing background gamma events that do not correlate with gamma sources located in the nuclear camera’s gamma-radiation field-of-view. The system is constructed for field use and includes a rugged laptop computer.

Benefits

•Assess sites remotely •Reveals unknown gamma activity •Localize hot spots of gamma activity •Determine isotopes that may be absent or present by their spectra •Reduce exposure to employees •Monitor distribution of activities

Limitations

Gamma Energy Range: Less than 30 keV to greater than 1.5 MeV
