Recently, for the suit of electromagnetic radiation of Chinese mainland (known locally as radiation suits, or radiation maternity), ESMMC conducted a field shop unannounced visits, sampling activities. ESMMC sampled the product storage, and entrusted with maintaining long-term relationships globally recognized laboratories for product quality assessment. This is results of the evaluation.
Evaluation results are translated into scores (PETS), each critical point to 20pets out, the following are survey results, press out successively in the order presented
he rise of technology allows us to enjoy unexpected life experience. However, electromagnetic radiation brought by various electronic and electrical products has become a new concern. According to the ESMMC survey, more than 90% of women will purchase radiation-proof clothes when preparing themselves for pregnancy in response to the increasingly complex environment exposed to electromagnetic radiation.
Radiation protection maternity wear of unique materials and reasonable design can adapt to physiological changes of pregnant women and shield them from radiation, thus gaining great attention among pregnant women. Brands of radiation protection clothing such as U+ (Youjia) and JOYNCLEON have become the hot topic of conversations among expectant mothers.
The questionnaire aims to the pregnant women in 71 hospitals from Beijing, Shanghai, Guangzhou and other cities. A total of 6000 questionnaires were distributed including 3652 questionnaires acquired and 3541 effective questionnaire
Spin-related effects in metals and in ferromagnetic heterostructures are generally robust and observable at room temperature.
Reduced dimensionality, confinement, and reduced scale often lead to magnetic structures and spin behavior that is markedly different from that of the bulk.

The 2014 Annual Meeting of the Electromagnetic Shielding Technical Steering Committee (ESMMC) will be held in Paris FR, bringing together experts across a wide range of fields to present new developments in electrostatics shield.
