The measuring methods for determining the shielding effectiveness of radiofrequency (RF)-protective clothing are defined in German Standard DIN 32780-100. According to this standard, both the electric and the magnetic shielding effectiveness are measured in order to calculate the electromagnetic shielding effectiveness. The electromagnetic shielding effectiveness is an adequate quality criterion for the degree of protection and also compares well with the Specific Absorption Rate (SAR). In this article, the impact of different design features on the electromagnetic shielding effectiveness is analyzed. The electric shielding effectiveness of the used shielding materials is measured according to MIL STD 285 and thereupon taken into account. Moreover, different parts of the RF-Protective Clothing are analyzed in terms of shielding properties. The main focus is on the question to what extent seams and zippers impair the shielding properties. Therefore, two RF-protective suits with different design features are tested and compared. One of the tested suits is accredited according to German Standard and is already on the market. The other one is an optimized prototype. Weak spots concerning design features and starting points for further optimization are worked out. [ABSTRACT FROM AUTHOR]
