Chapter 5: Features of Portable XRF Devices and Their Safe Handling

Recently, the use of portable XRF instruments has been expanding. Portable XRF devices include plug-in types that require a power source and handheld types that are battery-powered and can be carried anywhere. In this chapter, the features of these portable XRF devices will be described in comparison with floor-standing devices and benchtop devices. Although the handheld type of equipment is very convenient, it is advisable to carefully consider whether it is really necessary to use it as the user may be exposed to radiation depending on the shape and condition of the sample. Considering these points, the optimum device selection according to the characteristics of the sample will be discussed.
