GlobaLog® is the world’s most advanced and most precise tool for managing the risk of overexposure to cosmic radiation.
The ‘brain’ of the GlobaLog® system is an advanced relations database able to handle the complex interplay of five key factors affecting individual exposure to cosmic radiation.
- Duration of flight. The GlobaLog® system generates individual accumulated dose readings based on air-time information only. This information is received automatically from client airlines via a data exchange module.
- Minute-by-minute variations in cosmic radiation. Variations in cosmic radiation occur over a range of time scales: The 11-year solar cycle, daily fluxes and solar-originated disturbances which vary from minute to minute. Average readings are therefore imprecise measures of an individual’s exposure to cosmic radiation.
- Flight route. The earth’s magnetic field provides protection from cosmic radiation. But because of the structure and dynamics of the field, the level of protection varies with latitude. It is at its highest around equator, and at its lowest above the Polar Regions.
- Altitude. The earth’s atmosphere also provides protection from cosmic radiation. But the level of protection depends on altitude. The radiation level approximately doubles with every 6000 feet of increased altitude. The dose of radiation at the cruising altitude of jetliners is between 200 and 400 times greater than at sea level.
- Aircraft performance profile. The GlobaLog® system also takes into account the different performance profiles of various aircraft. This further increases the accuracy of the dose readings generated by GlobaLog®.
