Waste in the United States recognized the environmental issue that landfills create, and has been creating bans on U.S. landfill. Although this may create more environmental stability in the United States, it has become a major environmental and health issue in the countries to which the electronic waste is being shipped. Waste in the United States As a nation, Americans generate more waste than any other nation in the world, officially with 4.4 pounds (2.0 kg) of municipal solid waste (MSW) per person per day, with another study estimating 7.1 pounds per capita per day. Fifty five percent of this waste is contributed as residential
Counts per minute dose reading. This modifies the tube characteristic so each count resulting from a particular radiation type is equivalent to a specific quantity of deposited dose. More can be found on radiation dose and dose rate at absorbed dose and equivalent dose. Disintegrations per minute (dpm) and disintegrations per second (dps) are measures of the activity of the source of radioactivity. The SI unit of radioactivity, the becquerel (Bq), is equivalent to one disintegration per second. This unit should not be confused with cps, which is the number of counts received by an instrument from the source. One dps (one dpm)
