A radiation shield standoff comprises a support section having a mounting surface for an electronic component, with the support section configured to separate the electronic component a predetermined distance from a chassis wall. The standoff also includes a coupling section configured to couple the standoff to the chassis wall. A flange is located between the support section and the coupling section, with the flange configured to hold a radiation shield layer in place on the chassis wall and provide radiation shielding. A boss is located between the flange and the coupling section, with the boss abutted against the flange and smaller than the flange. The standoff also comprises a radiation shielding metal.
