radiation in perspective
by kenzi Buchanan
2.
Alpha radiation
Alpha radiation is a heavy, positively charged particle given off by atoms of elements like uranium.
Alpha radiation can be blocked by a piece of paper.
Rutherford discovered alpha radiation.
Alpha particles are slow compared to beta & gamma radiation.
3.
Beta radiation
Beta radiation consists of electrons.
A sheet of aluminum can stop beta radiation.
4.
Gamma radiation
Gamma rays are a form of electromagnetic radiation.
Gamma rays can pass into a human body, but can be almost completely blocked by concrete.
It travels the speed of light
5.
radiation
Radiation can be used in many different ways such as to make electricity, treat cancer, and in many more helpful ways.
6.
millirems
Radiation is measured in units called millirems. A millirem is a unit of radiation used to measure exposure to humans.
7.
more millirems
1,000 rem exposure to the whole body is normally fatal, but this dose level is used for some medical treatments of small portions of the body.
8.
mrem (millirems)
10,000 mrem is the minimum annual radiation exposure linked to increased lifetime risk of cancer.
Anything below 100rem scientist believe that that's permanent effects.
9.
Increasing millirems
You increase your dose by a millirem by: -an average year of TV watching -a year of wearing a luminous dial watch -a coast-to-coast airline flight -a year living next door to a normally operating nuclear power plant
