Facts found through the five physical senses to which a person can attest without further support

Question 13

Circumstantial evidence

Answer 13

Facts which support presumptions or inferences formed from direct or physical evidence

Question 14

Physical evidence

Answer 14

Material objects evaluated during an investigation which tend to prove or disprove facts

Question 15

Question 18

Alpha

Answer 18

-can be stopped by a sheet of paper
-do not penetrate skin
-harmful if ingested

Question 19

Alpha

Answer 19

Energetic positively charged particles emitted from the nucleus during radioactive decay that rapidly lose energy when passing through matter

Question 20

Beta

Answer 20

Fast moving positively charged protons or negatively charged electrons emitted from the atoms nucleus during radioactive decay

Question 21

Beta

Answer 21

-capable of penetrating the skin
-more hazardous when inhaled or ingested
-stopped by a layer of clothing, thin sheet of metal, or thick plexiglass
-travel further than alpha but cause less damage over equally traveled distances

Question 22

Gamma

Answer 22

High energy photons, often accompany the emission of alpha or beta particles from the nucleus. Weightless packets of energy like visible light and X-rays

Question 23

Gamma

Answer 23

-can easily pass through the human body or be absorbed by tissue
-concrete, earth, and lead may shield against radiation

Question 24

Neutron

Answer 24

Particles that have a physical mass but no electrical charge. Are highly penetrating

Question 25

Neutron

Answer 25

-soil moisture density gauges are a common source
-found at operating nuclear power plants
-shielding requires material with high amounts of hydrogen, such as oil, water, and concrete
