PURPOSE: To obtain a radiation analyzing apparatus having a simple constitution at a low cost, by providing an EDX/WDX address switch, into which the signals from a signal processing circuit, an angle reader and an ROI signal generating circuits are inputted.
CONSTITUTION: A second signal processing circuit part 3b forms and outputs wave height data A and a store signal B on the basis of the input signal from a radiation detector 1b. These signals, angle data θ or 2θ from an angle reader 2 and an ROI signal (f) from an ROI signal generating circuit 7 are inputted into an EDX/WDX address switch Z. Under the state the switch Z is used in the EDX (or WDX) state, the switch Z is alternately changed so that the stored signal and the wave height data, which are inputted from the circuit part 3b (or with the angle data inputted from the reader 2 as address data and the ROI signal from the circuit 7 as the store data), are supplied into a second multichannel analyzer 8b. Since expensive memory elements as constituent elements can be omitted, the apparatus can be constituted simple as a whole at a low cost.
