Dịch bài đọc:

Điện thoại di động phát ra sóng vô tuyến vi sóng. Các nhà điều tra đang đặt câu hỏi liệu việc tiếp xúc với các sóng radio này có thể dẫn đến ung thư não hay không. Cho đến nay, các số liệu không phải là cuối cùng. Bằng chứng chính xác không cho phép chúng tôi nói chắc chắn rằng điện thoại di động chắc chắn an toàn. Mặt khác, nghiên cứu gần đây vẫn chưa chứng minh được tác dụng phụ rõ ràng liên quan đến việc sử dụng điện thoại di động kéo dài.

Nhiều nghiên cứu hiện đang diễn ra ở nhiều quốc gia. Một số kết quả trái ngược nhau nhưng những kết quả khác đã cho thấy mối liên quan giữa việc sử dụng điện thoại di động và ung thư. Tuy nhiên, những nghiên cứu này là sơ bộ và vấn đề cần điều tra thêm, dài hạn.

Cho đến khi dữ liệu khoa học rõ ràng hơn, mọi người nên cố gắng không sử dụng điện thoại di động trong thời gian dài. Đừng nghĩ rằng điện thoại rảnh tay cũng an toàn hơn. Hiện tại, nghiên cứu thực tế cho thấy điều ngược lại và chúng có thể nguy hiểm như vậy. Người ta cũng nghĩ rằng những người trẻ tuổi mà cơ thể vẫn đang phát triển có thể có nguy cơ đặc biệt.
