Nowadays, many large examinations need to use mobile phone shielding devices. Many students and parents feel concern about the electromagnetic radiation effect of mobile phone shielding devices. This paper considers the comprehensive effect of mobile phone from the electromagnetic radiation intensity, the main radiation direction and the distance with the radiation source. This paper designs the exam electromagnetic radiation prediction system of mobile phone shielding devices. By comparing the calculating results of prediction system with the real measuring results, the effectiveness of the prediction system can be verified. The electromagnetic radiation effect of mobile phone shielding devices is analysed quantitatively according to the China electromagnetic radiation standard. The paper provides the safe using distance of mobile phone shielding devices in the end. The quantitative study of this paper has the definite guide significance aiming to the mobile phone shielding devices's use.
