Radiation Safety in Industrial Hygiene

Nature has it that all living things depend on a certain type of radiation to survive. This is evident in many ways for instance we can see because our eyes sense and become aware ***** the radiation in the *****m of light; ********** there is infrared radiation that allows is ***** keep ********** warm in the cold weather, radiation is used for cook*****g, whether ***** is on the stove or in the microwave. Radiowaves are used for long distance communication by using sound or picture; and ultraviolet ***** is used for medical treatment or for putting on a good suntan. Even though some *****ms of radiati***** can travel long *****s, it can be stopped ***** employing the correct absor*****rs: starlight can transgress galaxies but ********** using a piece of paper it can also be stopped; radiowaves ***** ***** capable of travelling huge distances but can be absorbed by metal like substances. Just as light travels in straight lines, so does ionising radiation til it is ***** by materials.

It was back in the twentieth century, that "***** radiation" was discovered. Ionising radiation is found everywhere and supports our natural background radiation. It is also found in many sources such as ***** sun, outer-space, the rocks and soil beneath our feet, the buildings we inhabit, ***** air ***** breathe, the food and drink we consume, ***** even in our bodies.

Types and sources of ionising radiation

Inclusion to X-rays, are three types ***** ionising ***** called alpha, beta ***** gamma. Alpha rays also ***** the helium nuclei can be stopped ***** paper, beta rays also known as high-speed electrons ***** ***** less easily, and gamma ***** need lead or concrete to stop them. It is a known fact that since one ********** glow in the dark due to light similarly, a chest X-ray will not make one radioactive, therefore, ionis*****g radiations will not ***** one *****. This is because in industries in a reactor there are billions of free nuclear projec*****es called neutrons, which on absorption into any material cause it to ***** radioactive. Th***** leads ***** the material producing its own radiation.

A person's annual radiation dosage originates from the decay of ***** radioactivity because the presence of bricks ***** mortar escalates the concentration of a ***** gas ***** radon. Radon is produced naturally from ***** radioactive decay of uranium and thorium, ***** in *****, soil, *****, mortar, tiles ***** *****. Plunging ventilation to conserve energy in turn causes an increase in the radon concentration in the air we breathe. Another way to increase radon ***** is by using bore water, especially in hot showers. Other sources ***** smaller dosages of everyday radiation come ***** cosmic rays and from the natural radioactivity found in the consumption of our food and drink. The man-made sources of ***** are ***** the use ***** medical technology, such as ***** usage of X-rays for radiography and tomography, and radioactivity in nuclear medicine. According to a study, a person absorbs
