what is ALARA ? .............
ALARA is an acronym formed from the phrase “As Low as Reasonably Achievable.”The phrase refers to a principle of keeping radiation doses and releases of radioactive
materials to the environment as low as can be achieved, based on Technologic and economic considerations.
The following mitigation methods can often be a practical and effective means of minimizing external radiation hazards.
1. Time
Reduction of time of exposure can directly reduce radiation exposure.
2. Distance
Increasing the distance between you and the radiation source will reduce exposure by the square of the distance. This principle applies to sources of penetrating radiation (x-rays, gamma rays, or high-energy beta particles). Increasing distance
may not be necessary if the radiation is non-penetrating (alpha particles or low energy beta particles).
3. Shielding
Shielding a radiation source often involves additional economic considerations. It is not necessary to shield every source. However, shielding can effectively reduce radiation doses in some situations.
