Radiation Safety in MG Laboratory

 Every clinical staff that involve in radiographic procedures will be wearing radiation dosimetry badges especially radiographer. 

In radiography, medical dosimetry is the measurement of absorbed dosage and the optimization of dose administration. The radiation emitted by the sources is usually defined by depth dose curves and dose profiles assessed by a medical physicist in order to plan the delivery of radiation therapy. Calculations are made to translate the physical quantity absorbed dose into equivalent and effective doses, the details of which depend on the radiation type and biological context, in order to evaluate stochastic health risk.

ALARA. As Long As Reasonably Achievable.

ALARA is the radiation safety guiding principle. ALARA is an acronym that stands for "as low as reasonably achievable." This principle states that even if the dose is tiny, you should try to avoid it if it offers no immediate benefit. To do so, you can utilize three essential radiation safety measures: time, distance, and shielding. When you have an x-ray in your doctor's office or clinic, you can see how these principles function together. To protect themselves from the everyday exposure to radiation, the radiographer takes the x-ray image behind a barrier.

• Time: simply refers to how much time you spend in close proximity to a radioactive source. Limit your time spent near a radioactive source to only what is necessary to complete the task. There's no reason to spend any more time in its vicinity than is absolutely essential.
• Distance: refers to the distance between you and a radioactive source. As much as possible, keep your distance from a radioactive source. Because distance and dose are inversely related, this is a simple strategy to protect yourself. You can reduce your dose by increasing your distance.
• Shielding: to protect oneself from a radiation source, you must place something between yourself and the source of radiation. The most efficient shielding will be determined by the type of radiation emitted by the source. Examples of shielding: 

Lead apron and thyroid shield.

Gonad shield.
