What are X-ray safety precautions?
Avoid the primary X-ray beam. Wear protective equipment (e.g., lead aprons and thyroid collar, leaded goggles, leaded gloves). Use shielding (e.g., mobile shields, lead curtains), when possible. Be aware of the position of the beam.
What are the main risks of X-rays?
Risks
- a small increase in the possibility that a person exposed to X-rays will develop cancer later in life.
- tissue effects such as cataracts, skin reddening, and hair loss, which occur at relatively high levels of radiation exposure and are rare for many types of imaging exams.
What are the 3 basic radiation safety principles?
ALARA means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.
What type of hazard is X-ray?
Over exposure to X-ray radiation is detrimental to the living cells and may lead to development of life-threatening diseases. It is intuitive to postulate that a low level exposure may lead to functional abnormalities in human immune cells.
Why is radiation safety important?
Radiation protection is to prevent the occurrence of harmful deterministic effects and to reduce the probability of occurrence of stochastic effects (e.g. cancer and hereditary effects).
What are 5 effects of radiation?
Radiation Effects on Humans
| Dose (rem) | Effects |
|---|---|
| 5-20 | Possible late effects; possible chromosomal damage. |
| 20-100 | Temporary reduction in white blood cells. |
| 100-200 | Mild radiation sickness within a few hours: vomiting, diarrhea, fatigue; reduction in resistance to infection. |
What is radiation safety?
Also called radioactive safety, radiation safety is a combination of safe practices and precautionary measures put in place to promote safety when working with or near radiation. It follows the guiding principle ALARA or “as low as reasonably achievable.”
What is safe level of radiation?
The ICRP recommends that any exposure above the natural background radiation should be kept as low as reasonably achievable, but below the individual dose limits. The individual dose limit for radiation workers averaged over 5 years is 100 mSv, and for members of the general public, is 1 mSv per year.

What are 3 effects of radiation?
Harmful Effects of Radiation
- Hair. Loss of hair fall occurs when exposure to radiation is higher than 200 rems.
- Heart and Brain. Intense exposure to radiation from 1000 to 5000 rems will affect the functioning of the heart.
- Thyroid.
- Blood System.
- Reproductive Tract.
What are hazard signs?
Hazard pictograms alert us to the presence of a hazardous chemical. The pictograms help us to know that the chemicals we are using might cause harm to people or the environment. The GB CLP hazard pictograms appear in the shape of a diamond with a distinctive red border and white background.
What is radiation warning?
An officially prescribed magenta or black trefoil on a yellow background, which must be displayed where certain quantities of radioactive materials are present or where certain doses of radiation could be received.
Which Colour is used for radiation hazard?
Purple – used for radiation hazards. It may contain a combination of purple and yellow. Black & White – or a combination of the two are used to designate traffic and housekeeping markings.
What are the 4 types of safety signs?
These 4 important safety signs can be broken into categories: Prohibition, Warning, Mandatory and Emergency.
- Prohibition Signs. A sign prohibiting behaviour likely to increase or cause danger (e.g. “No access for unauthorised personnel”)
- Warning Signs.
- Mandatory Signage.
- Emergency Signs.
