Work Ergonomy

    The work ergonomy is very important in the workplaces; the people must choose the best options of postures to work.  The employers must give to employees a comfortable place to work and to be able to develop the work in a correct way.

     Much of the time the workers represent the most important part in an organization or company this is why we need to take care of their health, and the good ergonomic facts can help us to choose the better conditions to work.

Some tips for a good ergonomic in the work are:

All the things and working tools must be close you, this means that if you need the phone or paper you can get it without any uncomfortable actions.

·         The screen of the computer must be in front you.

·         The light in the working place must be the correct one, try to use natural light.

·         The keyboard must be in front of you where your hands can use it in a comfortable way.

·         If you write with the left hand the mouse must be in the left side of your desk, but if you write with the right hand the mouse must be in the right side of your desk.

·         The chair must be adapted to desk in order to obtain a good combination and you can support your arms in a good way.

·         If you are a short person you must search things that when you use them they support your feet.

·         Your arms and your laps must be form an angle of 90°.

·         Awkward Postures in the office work.

Here an example of good practices:

In the workplace we take some bad postures for example:

·         Lack of Back support

·         Lack of support at elbow and wrist.

·         Not enough light in the office.

·         Not enough space.

·         The things that you need are far away from you.

Ionizing Radiation

Radiation is the energy spread; the ionizing radiations are particles flow. Also the radiation is composed of electromagnetic waves; it forms from the presence of magnetic and electrical camp. We can find two types of radiation: natural radiation that comes from sun or nature resources and another kind of radiation is the artificial radiation this is the radiation created by humans.

The ionizing radiation is dangerous because it has enough energy to break up an atom, it also forms ions. Some examples of ionizing radiation are the gamma, X rays and alpha, beta particles.

The ionizing radiation represents a risk for human biology for example:

·         They can interact with the human cells.

·         The effects do not present immediately they present months later.

·         It damages cells.

·         It causes the death cells.

·         It causes extern irritation.

·         It causes contamination.

·         It produces problems in workers blood.

·         It causes problems in digestive system, in the skin, in the penis and testicles of men, in the ovary, in the eyes, heart health, bones, and lungs

To sum up we need to know that there are different kind of exposition to ionizing radiation for example we can be exposed at job, in the hospital, at home.

 In medicine we are exposed when: we apply different treatments like radiology or radiotherapy, in the industry employees are exposed when in the work places are producing energy. Some places of works like hospitals that bring medical treatments for cancer, different types of work where the temperatures are high,  a lot of jobs are where the workers need to manipulate radioactive materials, mines industries can be exposed to ionizing radiation that it is a lot of energy that are emitted from the soil or building materials as a result a lot of dangerous in the work place for example it can produce mutations, and alterations in DNA, also can damage some tissues and singles organs, in addition it can produce cancer.

I considered  that video  important because a lot of workers are exposed to ionizing radiation, most of all, I think that this video give us a lot of important information about how this kind of radiation is produce, it is interesting to listen and watch the video and know how  ionizing radiation is produced. The ionizing radiation can be in the sun, in factories that produces high temperatures, the hospitals when the doctor apply radiology, in addition some common ionizing radiation are: alpha, beta and gamma.

To conclude I think that this video is very important because workers are not the only ones exposed, we are exposed too in the houses, college, in another places so for that we need be careful with ionizing radiation and take simple preventions like:

·         No exposed a lot to the sun.

·         Take prevention in my work place and avoid ionizing radiation

·         Surveillance

·         Use individual protective equipment.

·         Good solid waste management.
