A radioisotope excited XRF method based on the use of five 10‐mCi 125 I point sources arranged in a newly designed configuration is applied to the bromine determination in very small blood serum samples (⩽50 μL). The possibility of determination of 0.05 μg Br in blood serum during 100 s counting time with a standard deviation of ±10% is described. The simplicity and low cost of the present method are major advantages over the other nondestructive methods and render it suitable for medical laboratories.
