2. the condition of being subjected to something, as to infectious agents or extremes of weather or radiation, which may have a harmful effect.
3. in radiology, a measure of the amount of ionizing radiation at the surface of the irradiated object, such as a person's body; calculated by multiplying milliamperage times exposure time in seconds, expressed in units of milliampere seconds (mAs). See also x-rays.
x-ray exposure see exposure (def. 3).

ex·po·sure

(eks-pō'zhūr),
1. A condition of displaying, revealing, exhibiting, or making accessible.
2. In dentistry, loss of hard tooth structure covering the dental pulp due to caries, dental instrumentation, or trauma.

Epidemiology A state of contact or close proximity to a chemical, pathogen, radioisotope or other other substance by ingesting, breathing, or direct contact—e.g., on skin or eyes; exposure may be short term—acute—or long term—chronic

Imaging An image, such as an anteroposterior exposure of the chest
Medical liability The degree of malpractice risk borne by a health care provider while performing a particular medical service
Nuclear physics The amount of ionising radiation in air from X-rays or gamma rays at a specific point in space, defined as the total charge of ions divided by the mass that would completely stop the radiation; the SI unit for exposure is coulomb per kg—C/kg; in human terms, exposure refers to the amount of ionizing radiation to which a person has been subjected

Patient discussion about exposure

Q. I feel some effects due to less exposure to sunlight. I heard that UV lighting is effective for depression. I’m living in northwest pacific; the summers are very nice but way to short. I feel some effects due to less exposure to sunlight. I have been told that sun light helps the production of the chemical in the brain that we are deficient of. If true, are there certain types of fixtures and/or bulbs that I should try.

A. Its also called seasonal affective disorder:

(SAD) depression with fatigue, lethargy, oversleeping, overeating, and carbohydrate craving recurring cyclically during specific seasons, most commonly the winter months.

I would about UV. Perhaps you should get a fluorescent light fixture for the area where you spend the most time each day and turn it on.

The web sites that sell the commercial light boxes want several hundred dollars or even more. (Seems like rip off to me.)
The web page at
http://www.ncpamd.com/seasonal.htm

says "studies suggest that regular fluorescent lights will work as well. UV (ultraviolet) light can damage eyes and skin, so it must be filtered out. It is best to buy a commercially built light box to be sure of the exact amount of light and to be sure that there are no isolated "hot spots" which could damage eyes. Many people still prefer full spectrum (minus UV) light because it i

Q. how do i keep my baby as minimal as passable exposed to the out side world threats? like decease and other things

A. It might seem like a caring attitude, but I'm not sure it's neither possible nor absolutely necessary - babies do get sick, usually only mildly and transiently, so trying to prevent all the cases of fever would be quite impossible.

What you can do, is to maintain the regular infant welfare visits, give him or her the necessary vaccinations (one of the most important things you can do for your child), make sure your baby eats well, regarding both the amount and type of foods, and generally keep a good hygiene: make sure to wash hands after you go to the toilet and before you handle your baby, don't expose him or her to other sick infants etc.

However, all this is just a general advice - if you have specific question you may want to consult your doctor (e.g. a pediatrician).

Take care,
