During the 20th century, mobile phones radiation became an important source of concern for scientists and physicians about their potential health hazards and also interferences in medical laboratories. The emitted microwaves from such phones have been shown to have many effects upon the behavior, sleep, immune function, central nervous system, cancer, children, cardiovascular system, reproduction and development. Moreover, they can physically cause electromagnetic interference in medical environments; can also cause errors in immunoassays in laboratories. This book is focused on interferes by the cell phones exposure during immunoenzymometric assays such as; quantitative determination of human chorionic gonadotropin, human ferritin and human triiodothronine (T3), and also it discussed whether the medical equipments, i.e. ELISA reader, could be interfered by the exposure to the cell phones in the laboratory. As the title indicates, the book is primarily intended for radiation scientists and physicians although it will also benefit for almost everyone in the world even on those who do not have a mobile phone.
