1.Warm objects release infrared, because of that, it can be used in emergency situations like locating a person trapped in a collapsed building, but improper use of this wave may pose danger in what way?

2.Sun is a natural source of UV light. It helps our body produce Vitamin D which is needed to have healthy skin. What could be the danger if a person is overly exposed to this UV light? *

3.X-ray is being used in hospitals because it has high frequency and energy which allows it to penetrate our body and see our organs and bones. However, pregnant women are not allowed to have X-ray check-up. Why do you think so? *

4.Gamma rays are being used in treating cancer through radiotherapy. But improper use of this wave may also cause what danger? *

5.Radio waves and microwaves are used in telecommunication. However, they pose certain effect on birds. In what way they can cause danger to these animals? *

Direction: Identify the possible negative effects of improper use of EM waves in the following situations. pa sagot po ng Tama at matino please

1. Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the infrared. Even objects that we think of as being very cold, such as an ice cube, emit infrared. ... The warmer the object, the more infrared radiation it emits.

2. The skin uses sunlight to help manufacture vitamin D, which is important for normal bone formation.

3. A healthcare provider may recommend x-rays to look for bone fractures, some types of tumors, injuries or abnormal masses, and signs of pneumonia in the lungs. Dentists take x-rays to check for cavities or other dental problems.

4. Gamma rays are mostly used in the radiotherapy/ radiooncology to treat cancer. They can also be used to spot tumours. Gamma rays can kill living cells and damage malignant tumor. The Gamma radiation intensity decreases exponentially with the depth of penetration.

5. "Birds are known to be sensitive to magnetic radiation. Microwaves can interfere with their sensors and misguide them while navigating and preying,�� says Daniels.
