1) X- rays
* television
*computer monitor
* only those TV and computer monitors that uses cathode ray tubes. The flat screens nowadays do not use cathode ray tube so they do not emit X-rays.

2) electromagnetic radiation *phones
* the radiation emitted by phones are not too strong, Although they make our cheek warm but it is not strong enough to cause damage to the tissues.

3) UV rays
*the sun
*fluorescent lights
* UV from the sun can be the main cause of skin cancer also other damages such as sunburn, tanning, premature ageing and eye damage
* UV rays emitted by fluorescent light are low compared to the sun ad they are safe under normal use.

ELECTROMAGNETIC WAVES- a.) Non-ionizing
- radiofrequency =very small frequency emitted by cell phones and absorbed by tissues.
-microwaves = used in cooking. it produces heat that could cause damage to tissues.
b.) Ionizing
- x-rays = used in medical procedures such as dental and chest x-rays. small amount is also given off by television.
- radon = a colourless and odourless gas produced naturally from the earth's crust. extensive exposure to radon could be harmful.
c.) UV rays
- UV radiation from the sun can either be ionizing or non-ionising depending on the wavelengths. The level of damage by UV ray also depends on the wavelength.

1. Ionizing radiation that comes from X-rays and nuclear reactions
- causes cancer and birth defects
- from television
2. Carcinogens
- arsenic, benzene, hydrogen cyanide
- increase risk of cancer
- from smoking cigarettes
3. Non-ionizing radiation from radio frequency waves
- from cell phones
- lower power radiation source than x-ray machines
4. UV rays

What source and type of radiation are we exposed to daily?

Television and Computer – Xray but flat-screen TVs and computers do not produce Xrays as they don’t use cathode ray tubes.

Drinking Water – source of water that near to the power plants is highly vulnerable to contamination with radioactive waste water.

Consumer Products (cell phones, clocks) – Infrared, they give off radio frequency (RF) waves that are not strong and will not give bad effect on the users.

Soil – Radioactive particles (radionuclides) end up getting released from the soil as gas and we inhale.

Radon – Radioactive gas that might be at home. It might release through the creeps of floor from natural decay of uranium. It is one of the causes of lung cancer.

Plane Travel – Cosmic radiation from the outer space.

Scanner in Airports – Exposed Xray to the body.

Medical Imaging – It uses radiation to diagnose diseases including CT Scans and mammograms.

Cigarette Smoking – Radioactive material that comes from natural sources and fertilizers used on the tobacco plants.

Sunlight – UV radiation from sunlight will not give bad effect to organisms but over exposure may cause skin cancer.

Thank you :)

- Television and cellphones
- Medical Imaging Procedures (Dental or chest X-rays)
Ionization Radiation

- comes from X-rays and nuclear reactions.
- Naturally-occurring radioactive elements in the soil and stones.
- Human receives internal exposure from radioactive elements which we take into our bodies through food and water, and through the air we breathe
Non- ionization radiation
- Radiofrequency waves from cell phones, Wi-Fi and microwave oven.

1. Microwaves, Wi-Fi and cell phones
- emits radiofrequency waves
2. Television

Daily radiation we exposed to:

1. TV and computer monitors
Contain a cathode ray tube which are capable of creating low-level X-rays

2. Drinking water
Contain low levels of radiation. It can pick up radiation from natural sources like rocks and soil

3. Natural gas
The one used for cooking, heating and other purposes may expose to radiation

4. Consumer products
Cell phone give off radio frequency (RF) waves that aren’t as strong as X-Rays

5. Soil
Radioactive particles which is radionuclides in soil are either remaining from the Earth’s original crust, introduced by cosmic radiation

6. Radon
It often creeps in through the floor or walls from natural decay of uranium in the ground

7. Medical imaging
The techniques to diagnose medical conditions use radiation such as chest X-Rays and dental X-Rays deliver about 10 mrem

8. Cigarette smoking
The smokers inhale small amounts of radioactive material which are from both natural sources and the fertilizer used on the tobacco plants
