What is radiations or Radiography and its types hazards of radiations and its precautions ?

Radiations

Radiations is the transmission of energy in the form of waves or particles through a material medium.

Types of Radiations:

Ionizing radiations

These radiations are high energy particles and more harmful for the environment e.g Alpha, Beta, Gamma, X-rays and neutrons.

Non-Ionizing radiations

These radiations are low energy particles and less harmful for the environment e.g Ultraviolet, infrared, radio waves, micro waves, & laser.

Radiography

Radiography is a process in which energetic particles or energetic waves/ ionizing radiations usually (x-rays, or gamma rays) travel through a medium or space of a metal or a variety of microwaves products, and an image is produced when the test object is exposed to these rays Radiography is used to know the internal structure of the metal, ensure product reliability of  and for the detection of the cracks in the metal object.

Hazards of Radiations

l Radiation sickness (radiation poisoning) if the dose is fatal, death usually occurs with two months.

l Loss of hair

l Eye cataracts

l Skin reddening, blistering & ulceration

l Sterility

l Nausea, vomiting, and leukemia

l Cancer as leukemia, cancer skin, etc

Monitoring of Exposure:

Environmental or personal monitoring by

l Film Badges- after the fact measurement, developed weekly or monthly

l Geiger counter-best for high energy beta, gamma

l Scintillation counter- used for wipe Surveys

Proper Disposal:

Of radioactive wastes and affected PPE

Training and Supervision:

Train and supervise workers dealing with ionizing radiation such as radiographers at sites

Good personal Hygiene Practices:

Washing and showering after work.

There are three factors to control exposure to radiation:

1. Time: Reducing the time of an exposure reduces the effective dose proportionally.

2. Distance: Increasing distance reduces dose. It is like handling a source with forceps rather than fingers.

3. Shielding: An effective barrier can provide needed protection from diarrhea like PPE, wall, screen, etc.
