Negative impacts of 4G frequency studied by BAU researchers

A group of researchers from Bangladesh Agricultural University (BAU) has studied the effect of 4G frequency on animals.

Teachers from the Department of Anatomy and Histology, Prof. Muhammad Rafiqul Islam and assistant professor Dr Imam Hasan, used 4G frequency on mice to see the effect of 4G frequency on animals.

Professor Dr Mohammad Rafiqul Islam and Assistant Professor Dr Imam Hasan of the Faculty of Veterinary Science at Bangladesh Agricultural University (BAU) have researched the impact of 4G frequency on mice.

Elevated Plus Maze System

The research indicates that exposure to 4G frequency has led to the generation of anxiety in mice, accompanied by changes in blood, kidneys, liver, testes, and brain compared to the normal state. 

To research the 4G frequency’s physiological and biological impact, researchers used the Elevated Plus Maze method. This method has revealed anxiety in the second and third groups, which are exposed to the frequency.

‘21 Swiss albino mice were divided into three groups. Besides the first group, the second group was exposed to 40 minutes, and the third group was exposed to 60 minutes of daily 4G frequency for a continuous two-month period. A 4G mobile was kept in dial mode near the mice as the source of the frequency during the experiment’, said Professor Rafiqul Islam.

Histo Patho logical Slide

He further explained that histopathological examination revealed some changes in the blood composition of the mice in the second group compared to the control. There were also alterations observed in the size of the seminiferous tubules in the testes, blood clotting in the central vein of the liver, reduction in the size of the glomerulus of the kidney, and a decrease in the number of cells in the memory-forming hippocampus region of the brain. 

The impact of these parameters was more pronounced in the mice of the third group compared to the second group. The mice in the first group, which was not exposed to 4G frequency, showed normalcy in the above-mentioned aspects.

In response to the question of how safe 4G frequency is for humans, the professor stated that the research has been conducted only on mice. Conducting research on a larger scale and in a broader context would be necessary to understand the impact on humans.

The Bangladesh Agricultural University Research System and the University Grants Commission of Bangladesh funded the research. Professor Rafiqul presented the research at an international conference organized by the ‘International Brain Research Organization held in Spain in 2023’. The research received recognition among scientists from various countries around the world.
