3-1 Part 5 Exposure to Radiation

Radiation that has enough energy to knock electrons off of atoms and break bonds is called ​ (a)   Radiation.

• IONIZING
• NON-IONIZING

Match the image and description.

E stands for Energy

• Not enough E to knock e- off

• 
• Enough E to break bonds

• 
• Enough E to knock e- off & make ions

• 
• Not enough E to break bonds

• 

After the electron is knocked off by ionizing radiation, the atom becomes a(n) (a)   .

Categorize these examples of radiation as either NON-IONIZING or IONIZING.

Groups:

(a) NON-IONIZING

,

(b) IONIZING

• Radio waves

• Infrared

• Visible Light

• Microwaves

• Ultraviolet Light

• X-Rays

• Gamma Energy

The damage Ionizing Radiation does to DNA can lead to:

• tissue/cell damage

• mutations

• cancer/tumors

• All of the above

True or False: Exposing plant seeds to Ionizing Radiation in order to cause mutations in the DNA is always harmful to the plant.

• True

• False

Food is hit with ​ (a)   energy/radiation in order to ​ (b)   bacteria & other pests, to ​delay ​ (c)   , and to ​ (d)   shelf life.
