•4.5 lbs per person per day

This is what the slide says?

Question 2

5 legal methods of solid waste disposal

Answer 2

Municipal incineration, source reduction, recycle and reuse, landfill, pyrolysis(baking your garbage)

Question 3

Process of composting

Answer 3

Removal of non-biodegradable items
Biodegradable waste is grinded to increase surface area
Waste is turned to allow aeration
Moisture can be added
Sludge can be added

Question 4

Mosquito development process

Answer 4

Eggs laid on water or just above water line
Larva and pupa stages of development occur in water but need access to air
Adult stage is the flying insect
prefer temperature of 80-90*

Hydroelectric-
Wind power
solar power 
geothermal power
wave power

Question 18

Measuring radiation levels

Answer 18

Most familiar operate on the principle of gas ionization… the GM counter, proportional counter, ionization chamber instrument. scintillation detector is primarily a laboratory based instrument. dosimeter indicates cumulative exposure indicates cumulative exposure to radiation over time.

Question 19

Entry route

Answer 19

inhalation, absorption, ingestion, parenteral(injection)

Question 20

Threshold dose

Answer 20

The dose at which a response can be measured

Question 21

Disposal of low-level radioactive waste in the U.S.

Answer 21

Hazardous Waste Disposal via Secure Landfill
Chemical/Physical/Biological Treatments:
▪Chemical: neutralization (making materials inert), precipitation (condensation of a solid from a solution during a chemical reaction), solidification (turning the liquid into a solid), or oxidation reduction (changes the structure of the substance)
▪Physical: evaporation or compaction
▪Biological: microorganisms used to decompose toxic organic compounds

Question 22

Depleted uranium (as discussed in class)

Answer 22

Has to be changed to a powder form to be stored, and gets more radioactive over time.

(I think there might be more but this is what I had in my notes)
