Single-photon-emitting or positron-emitting radionuclides employed in nuclear medicine are detected by using sophisticated imaging devices, whereas simpler detection devices are used to quantify activity for the following applications: measuring doses of radiopharmaceuticals, performing radiotracer bioassays, and monitoring and controlling radiation risk in the clinical environment. Millicurie sources, on the other hand, are 1000 times stronger and must be handled in a safe manner. The total charge produced by the passage of an ionizing particle through the active volume can be collected and measured. 2 offers from $68.98. When radiation enters the cylinder, electron-ion pairs are created (either directly or indirectly, depending on whether the radiation is a charged particle or neutral). DETECTOR The detector consists of a course grating of fine wires in close proximity ( 1 mm) to a ground plane. A beta particle is an electron ejected from the nucleus of a radioactive atom.

Whatever your area of interest, here youll be able to find and view presentations youll love and possibly download. The closest distance for a P&E detector is 30 cm or so from the load (but this is rare because of the harsh environment) and the farthest is 23 m. This is a ratio of almost 6000 times with r 2 scaling. The half life of Ra-226 is 1602 yr.Detectors:The net result of the radiation interaction in a wide variety of detectors is the production of electric charge (either directly or indirectly) within the detector. Along its axis is suspended a conducting wire to which a positive high voltage (usually about 900 volts) is applied through a resistor. The alphas ionize the air and these ion/electron pairs are accelerated by the strong field.
