Radiation Hazards Flashcards
What are the two different categories of Radiation?
Non-ionizing Radiation and Ionizing Radiation.
Where would you find the different ranges of electromagnetic waves?
- Radio/Television waves
- Microwaves
- X-rays
- Gamma Rays
Name four sources of Non-Ionizing Radiation?
Sources of Non-Ionizing Radiation include;
- Transmitting antenna farms
- Radar installations
- Electronic equipment using high voltage
- Electricity pylons
- Microwave ovens
- Lasers (higher level).
Name three effects of Non-Ionizing Radiation?
Effects of Non-Ionizing Radiation;
- Redness and burns to the skin
- Heating and damage to internal body organs
- Temporary or permanent eye damage
- Increased risk of skin cancer
- Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating. This is because of the relative lack of available blood flow to dissipate the excessive heat load.
The effects are mainly non-cumulative.
Name two sources of Ionizing Radiation?
Sources of Ionizing Radiation include;
- X-Ray machines.
- Nuclear power stations.
State three effects from Ionizing Radiation?
Effects of ionizing Radiation;
- Sickness and Diarrhoea
- Anaemia due to red blood cell damage
- A reduced immune system due to white blood cell damage
- Cancer
- Genetic mutations
The effects are cumulative
State the three Radiation Control Areas?
Radiation Hazard Control Areas
- RF Safe Area: No hazard deemed to exist.
- RF Restricted Area: Restricted to authorised personnel only.
- RF Danger Area: No access.
Who is responsible for Radiation matters on Station?
Contact the Radiation Safety Officer (RSO) for any queries regarding Radiation Hazards on Unit.
He is a specialist officer and can give you advice on RA issues.
