How many of us aware that when we are up there in the sky, we are exposed to cosmic radiation? The more we are flying the more exposure we will get.
In Malaysia, none of the airlines have adopted or implemented a policy to limit the exposure. this may be due to lack of knowledge, expertise, regulations etc ..........
Cosmic radiation dosages are shown in milliSieverts (mSv) or units of one thousandth of a Sievert. Cosmic radiation dosages are calculated using the CARI-6 computer prediction series developed by the US FAA. The International Commission on Radiation Protection (ICRP) limit for non-classified workers, such as Flight crew, is 6 mSv for a rolling 12-months. For additional safety margin considerations, certain companies has established a lower internal action limit of 4.8 mSv for a rolling 12-months. If a crew is found to exceed this internal action limit, the roster will be managed individually to ensure that the cumulative 12-months cosmic radiation exposure does not exceed 6 mSv. The above ICRP limits and the said company thresholds are for occupational exposure of cosmic radiation that is in addition to the normal background radiation of about 2mSv per annum.
So guys, especially who work for LCC or main income derived from flying hours, stop for a second and consider this threat. It is your health and future ..........
Just a thought.
