It is now standard practice to use radiation to sterilize medical products such as syringes. Radiation may also be preferable to heat for sterilizing bandages and ointments, which can be damaged by high temperatures. In industry, radiography is used in much the same way as doctors use x-rays. This technique is used to locate defects in metal casings and welds that might not show up otherwise, and to determine microscopic thicknesses of materials such as metal foils. Radiography can also be used to locate structural defects in statues and buildings.
Radiation has applications in a variety of other fields.
We use it to test the authenticity of art and date prehistoric objects accurately. We also use it to prevent certain foods from spoiling without significantly reducing the nutritional value, or making the food radioactive. A Natural Energy Force Radiation has been a part of our environment since the earth was formed. Yet, we have only learned of its existence in the last century. Through research and education, we have learned about its effects and potential hazards.
