Evaluating Claims About Absorption of EM-Radiations (Essay Sample)

Evaluating claims about absorption of EM-radiations
Day 1: choose claim, obtain and evaluate source
Claim 1: Operating microwave oven exposes harmful radiations.
Claim 2: 5G network employ millimeter waves in addition to microwaves and long term exposure could increase risk of cancer.
Brief outline of claim 1:
although microwave oven best example given by science for better living that helps mostly in kitchen but there are four reasons due to which microwave oven called to be dangerous:
1 Microwave oven makes food radioactive and emit rations (fall on electromagnetic spectrum). These radiations are if small, high frequency wavelength then these are harmful. Microwave oven radiates microwaves that may be ionizing and non-ionizing.
2 Microwave radiations (with frequency 3 to 10MHz used in ovens) destroy nutrients of food.
3 These radiations causes plastic bowl to emit chemicals.
4 Sometimes, microwave radiations kills beneficial food.
Brief outline of claim 2:
5G uses millimeter waves with frequency range 24GHz to 100GHz. These waves are electromagnetic and different from microwaves that have band-gaps just below the millimeter waves. 5G causes exposure and cancer risks due to three reasons:
1 As compare to low frequency field, the millimeter waves not penetrate beyond the skin’s outer layer. Therefore deep tissues are not heated. When tissues are heating there is primary potential that causes exposure towards the field of radio-frequency (RF) and built cancerous cells.
2 People continuously receives more RF exposure from their smart phones now.
3 MMW are absorbed by surface layer of cornea of human. It causes exposure which has great impact on nervous system, cardiovascular system. It also causes exposure of skin which become a cause of cancer through MMW.
Day 2 & 3: Summarizing the evidence
Claim 1:
Cause of claim 1:
Microwave radiations with small, high frequency wavelength (ionizing radiations) become causes harms. Harms of oven are observed in case if protective shield is weak and also if radiations are allowed to travel randomly.
Effects:
When radiations move randomly, it
