2. Tow types of radiations
● Non-Ionizing radiation
➩Refers to any type of electromagnetic radiation that does
not carry enough energy per quantum to ionize atoms or
molecules—that is, to completely remove an electron from an atom
or molecule.
● Ionizing radiation
➩The action of the substance, either directly or indirectly
ionizing the material (ionization effect) that the ability of ionizing

3. Non-ionizing
Radiation Source Wavelength Frequency Biological effects
UVA Black light 318-400 nm 750-950 THz Eye: photochemical
Sunlight cataract
Skin: erythema,
pigmentation
Visible light Lasers 400-780 nm 385-750 THz Eye: photochemical
Sunlight & thermal retinal
Fire injury
LED Skin: photoaging

5. Radiation exposure
Radiation exposure is that the human body must be exposed to
the massive dose of radiation. It dies when the symptom is heavy.
Symptoms caused by exposure
● Leukemia
● Cancer
● Nausea
● headache

6. Nuclear bomb
Nuclear bomb is a nuclear
weapon that explodes it by the
nuclear fission reaction that
atomic nuclei such as the
uranium and plutonium. cause.
The power of an atomic bomb is
indiscrimination and a large
amount of Weapons of mass
destruction that are extremely
large compared with conventional
arms, and slaughtered.

7. Relation radiation from
nuclear plant and nuclear bomb
1. Uranium concentration
➩ The nuclear power plant doesn't explode like the
atomic bomb because the uranium concentration is
low.
2. Rapidity of response of nuclear material
➩ The atomic bomb does instantaneously though
nuclear power generation does the reaction spending
time.

8. Conclusion
1. There are two radiation, it is non-ionizing and ionizing.
However, only ionizing is harmful in the human body.
2. The nuclear power plant and the atomic bomb have a big
The bloodshed ability of the nuclear power plant is lower
than that of the atomic bomb.
