### exposure:

Occupational exposure
* account for the majority of trichloroethane toxicity.
* can occur in the manufacture, transportation and distribution of gasoline
  - through dermal contact and inhalation
* can produce a wide range of adverse effects on reproduction
* is one received by a person within a controlled area
  - usually by inhalation or absorption through the skin
* major source of lead intake for adults.
* occurs during mining, milling and processing
  - the mining, milling, production and use of sepiolite
  - primarily through breathing the chemical

Prolong exposure
* Most prolong exposure causes skin irritation.
* Some prolong exposure promotes germination.
* causes irritation

### exposure:

Radiation exposure
* Most radiation exposure is from natural sources.
* Some radiation exposure is unavoidable, such as the cosmic radiation from space
  - leads to birth defects
* can also damage the male sperm and female eggs and result in genetic defects
  - cause cancers in humans
* decreases as the square of distance.
* drops off drastically with increasing distance
  - quickly with distance
* is hazardous to fetus
  - measured with equipment known as dosimetry
  - similar to other X-rays
* limits the duration of X-ray imaging.
* occurs by diagnostic X-ray.

Radon exposure
* Any radon exposure has some risk of causing lung cancer.
* coupled with smoking significantly increases the risks of developing lung cancer.
* increases the risk of lung cancer more for smokers than for nonsmokers.
* is also an issue in uranium mines
  - similar to many environmental health risks
  - the second leading cause of lung cancer
* is, however, arguably the one cause of lung cancer that is easiest to prevent.

Severe exposure
* can cause death from throat swelling or from chemical bums to the lungs
  - or from chemical burns to the lungs
* can lead to convulsions and loss of consciousness
  - convulsions, unconsciousness, cardiac arrest, and death
  - internal bleeding, kidney and liver failure and pulmonary emphysema
  - shock, circulatory collapse, and death

Solarisation
* involves turning solar radiation into heat.
* is exposure

### exposure:

Solarization
* also controls other soilborne organisms such as fungi, insects, and certain weeds.
* are exposure.
* can also reduce populations of soilborne fungi pathogens and weed seed
  - control crabgrass if high temperatures are achieved
* depends on temperature, geographical location and the time of the day.
* is an effective soil disinfestation technique for strawberry production
  - another technique that can be used in summer to literally cook the pests
  - part of the natural aging process
* uses trapped solar energy to raise the soil temperature to that level.
* usually does a good job of ridding the soil of weeds.

### exposure | solarization:

Soil solarization
* can provide control of many soilborne diseases, nematodes, and weed pests.
* method that employs a transparent polyethylene cover to trap heat.
* uses the natural heat from the sun to reduce nematode populations.

Southern exposure
* can take advantage of winter sun and provide some protection against summer heat.
* have direct light all day long.
* means all day light and bright.

Sun exposure
* aggravates rosacea in many individuals.
* causes damage that can accelerate the aging process.

Systemic exposure
* are increased in elderly subjects.
* is limited following inhaled zanamivir administration.

Ultraviolet exposure
* can also damage and kill plants.
* decreases the proliferation.

Windage
* are deflections
  - diameters
  - drag
* is exposure

Expulsion
* are propulsion.
* is rejection
* is the delivery of the infant
  - punishment for gross immorality or insubordination
