In the article, “Effects of electromagnetic radiation on health and immune function of operators”, the authors address an experimental study on the topic of electromagnetic radiation and its impacts on the human kind. The scientists based their study on the observation that electromagnetic radiation might indeed have harmful effects on living organisms. The objective of the people who conducted the study was to find out if there were any effects of electromagnetic radiation on both physiological aspects and immune functions on the human body. The scientist set up their experiment by deciding on the experimental group and the control group. The control group was a set of 95 ordinary individuals, and the experimental group was a set of 205 operators exposed to electromagnetic radiation. One of the ways scientists measured the effects were through a questionnaire that was self-designed. Additionally, the scientists ran tests on electrocardiography (a measurement of electrical activity in the heart), the physical body of the participants, and the urine of each individual. To further increase the level of accuracy and precision, the scientists evaluated the blood that was circulating around the body including erythrocytes, leukocytes and thrombocytes. With the blood, it could be tested if there was any deviation from the normal number or morphology of chromosome (also known as chromosomal aberration) or any other abnormalities in the cells. Scientists found out that there were several effects on the health of the experimental group. Firstly, the group that was exposed to electromagnetic radiation constantly complained about how they felt. They stated that they were feeling giddiness, tiredness, dizziness, and even amnesia. Furthermore, as the experimental group’s working years increased, their headache got worse. Another significant change that was seen between both groups was that the exposed group had an increase in alanine aminotransferase (which is an enzyme that is increased as there is more liver damage). There was also an increase of urobilinogen, which is the result of the reduction of bilirubin, on the group exposed to the radiation. Chromosomal aberration could also be seen in the experimental group. The scientists concluded their experiment by stating that electromagnetic radiation might indeed cause physiological indices, genetic effects, and immune function instabilities, and health obstruction on the human bodies. Even worse, if the amount of time spent under this radiation increases, the effects are more detrimental. The scientists analyze the significance of the experiment by saying that the protection of operators under electromagnetic radiation should be strengthened. The findings of the scientist are significant because they proved that electromagnetic radiation has negative effects on the human kind which could help in future investigations. For example, today, scientists can run experiments on how electromagnetic radiation affects other living organisms other than humans based on this experiment.
