What should you do if you are exposed to radioactive materials?
What should you do if you are exposed to radioactive materials?
Exposure to large amounts of radiation over a short period of time can cause Acute Radiation Syndrome (ARS). If you have symptoms of ARS (skin burns, nausea, or vomiting) seek medical attention as soon as it is safe to leave your building or shelter.
What effect can high doses of radiation have on the human eye?
Possible side effects of radiation therapy The main concern with radiation therapy is damage to parts of the eye, leading to problems such as blurry vision, dry eye, cataracts, retinal detachment, glaucoma (increased pressure inside the eye), loss of eye lashes, problems with tear ducts, or bleeding into the eye.
How can the risk of radioactive materials be reduced?
Reducing radiation risks
- keep radioactive sources like technetium-99 shielded (preferably in a lead-lined box) when not in use.
- wear protective clothing to prevent the body becoming contaminated should radioactive isotopes leak out.
- avoid contact with bare skin and do not attempt to taste the sources.
What type of radiation is most dangerous inside the body?
Alpha particles
What part of day is sun strongest?
Time of day: UV rays are strongest in the middle of the day, between 10 am and 4 pm. Season of the year: UV rays are stronger during spring and summer months. This is less of a factor near the equator.
What time of year does the sunrise the highest?
The summer solstice for the northern hemisphere occurs within a few days of June 21 every year. It is on this day that the position of the Sun in the sky at noon is at its highest altitude of the year, and the position of the Sun at Sunrise and Sunset is farthest north for the year.
When during the year is daylight the longest?
The June solstice is the summer solstice in the Northern Hemisphere and the winter solstice in the Southern Hemisphere.
Where does sun rises first in the world?
East Cape
What are the four equinoxes?
So, in the Northern Hemisphere you have: Vernal equinox(about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer. Autumnal equinox(about September 23): day and night of equal length, marking the start of autumn.
Is solstice the same as equinox?
The biggest difference between the equinox and the solstice is that a solstice is the point during the Earth’s orbit around the sun at which the sun is at its greatest distance from the equator, while during an equinox, it’s at the closest distance from the equator.
Is the solstice always on the 21st?
The solstices always occur between June 20 and 22 and between December 20 and 23 with the 21st and 22nd being the most common dates.
