Occupational Health

The World Health Organization (WHO) defines occupational health as a multidisciplinary activity that promotes and protects the health of workers. This discipline seeks to control accidents and diseases by reducing risk conditions.

Occupational health
care is not limited to physical conditions of the worker, but also addresses the psychological question. For employers, occupational health support is a refinement of the worker and the maintenance of working capacity.

The most common of which must address occupational health are fractures, cuts and sprains by accidents, repetitive motion disorders, problems with vision or hearing and diseases caused by exposure to unsanitary or radioactive substances, for example. It also can handle the stress of work or labor relations.

Note that occupational health is an important issue for governments, which must ensure the welfare of workers and compliance in the workplace. For that often make periodic inspections seek to determine the conditions under which develop different types of work.

It is important to note that job insecurity affects occupational health. A company that has its workers in black (not having health care coverage), and which is inadequate physical space for work-threatening people’s health.

PRODUCTION OF ELECTROMAGNETIC RADIATION

electromagnetic radiationThe easiest and most commonly used to produce microwave radiation, is one who is to pass through the high frequency currents. It was the method used by Hertz in his famous experiments and the method is still used today in all transmitters.

In the minds of many technicians, radiation and high frequency power became synonymous. However, this view is not permissible and the thing seems obvious to some one wants to think it over.

The current high frequency radiation is no longer a current phone is a sound vibration. To move from one state to another, you must use a power transformer which is in the first case, a radiator or wave transmitting antenna, and in the second case, a loudspeaker.

An electrical circuit may be the site of a current high-frequency intense without any trace of radiation. It is therefore interesting to try to understand how we can move from a current high-frequency energy radiated.
