ช่วยเราแปลภาษาอังกฤษหน่อยค่ะ จนปัญญาแล้วจริงๆ จะใช้พี่กูเกิ้ลก้แปลงงมาก ช่วยหน่อยนะคะ แค่partแรกก็ได้ค่ะ
Over half the population has been the subject of an ultrasound scan. Sound seems simple but has far more uses than most people realise. Observing unborn babies and locating obstacles at sea are two uses for sound that we consider.
We have evolved to live in a world where background radiation from the Earth and from outer space is normal. We are now making radioactive materials deliberately. Some are useful for medical treatments or form the heart of a smoke detector. Others are a by- product of nuclear power. How we dispose of the radioactive waste from these activities is a cause for concern. This module looks at the various options and how science is keeping us safe from contamination.
