Individually or in groups of two (I'm also allowing groups of 3), select one of the devices from the list below which uses radiation and tell me how it works.


Prepare a simple PowerPoint presentation (less than 10 slides) explaining:

(1)               What is the purpose of this device?

(2)               How is radiation used in its operation?

(3)               Health hazards associated with the radiation in this device?

(4)               Other interesting facts.

(5)               Picture of the device


Your power point should contain only graphics, labels, titles and point form notes.   Reading large blocks of text from prepared notes or from the power point will not be allowed during the 10 minute presentations.

Presentation dates:
Students will have one more work period in the computer lab room 119 on Monday, June 7th.   Presentations will be starting Tuesday, June 8 and continue until everyone is finished.   The presentations will be a minimum of 10 minutes long, although longer presentations won't be a problem.



Non-ionizing radiation: this type does not contain enough energy to detach electrons from atoms or molecules to form ions.

Ionizing radiation: this type is energetic enough to detach electrons from atoms or molecules, forming ions. This type is also powerful enough to damage living cells.
