Some children are watching shows with parents or siblings, and some are watching alone. On average, children younger than 2 years watch televised programs 1 to 2 hours/day. 2 Fourteen percent of children aged 6 to 23 months watch 2 or more hours/day of media.
- Both samples completed similar measures of television viewing and video game playing. 26 Television exposure was based on the average time spent on weekdays during 4 time periods (6 am to 12 pm, 12 pm to 6 pm, 6 pm to 12 am, and 12 am to 6 am) and separately on weekends during those same 4 time periods. These questions were then repeated for.
- However, only a small percentage of people in groups at increased risk from particle pollution (16 percent of adults with asthma and 5 percent of adults 65 years and older) were advised to pay attention to the AQI by a health care professional (Kansas Department of Health and Environment, 2006).
As the x-ray beam progresses through the body, it undergoes attenuation. The rate of attenuation (or penetration) is determined by the photon-energy spectrum (KV and filtration) and the type of tissue (fat, muscle, bone) through which the beam passes. For the purpose of this discussion, we assume a body consisting of homogeneous muscle tissue. In the following figure, lines are drawn to divide the body into HVLs. The exposure is reduced by a factor of one half each time it passes through 1 HVL. The thickness of 1 HVL depends on the photon-energy spectrum. However, for the immediate discussion, we assume that 1 HVL is equivalent to 4 cm of tissue. A 20-cm thick body section consists of 5 HVLs. Therefore, the exposure decreases by one half as it passes through each 4 cm of tissue. At the exit surface, the exposure is a small fraction of the entrance surface exposure.
Typical Exposure Pattern (Depth Dose Curves) for an X-Ray Beam Passing through a Patient's Body
The exposure to a specific organ or point of interest within the direct x-ray beam depends on its proximity to the entrance surface.
Tissue located outside the primary beam receives some exposure from the scattered radiation produced within the beam area. The scatter exposure to the surrounding tissue is relatively low in comparison to the exposure levels within the primary beam.

Exposure to noise should be controlled so that the exposure is less than a max combination of exposure level and duration
According the National Institute for Occupational Safety - NIOSH - the exposure to noise should be controlled so that the exposure is less than a max combination of exposure level - L - and duration - t.
The maximum time of exposure at a noise level can be calculated as:
t = 480 / 2(L - 85)/3 (1)
