There has been several works on magnetic basement depth determination using aeromagnetic data. However majority of these works has been done using the old data of 1970's with a flight line spacing of 2km, average terrain clearance of 150m, and a nominal tie line spacing of 20km and in map form which is of lower resolution. This work re-evaluated parts of Middle Benue trough Nigeria employing a more frequent automatic source depth technique in spectral analysis; and an old empirical depth method (maximum and half slope techniques) using the new high-resolution airborne Aeromagnetic...

There has been need to develop alpha and beta particle detectors capable of detecting alpha and beta radiations beyond their short range in air over 1km-square area of land. This research has suggested and explored two new and indirect principles towards achieving this.The first method discussed the possibility of tracking the ultraviolet and visible fluorescence light yield from their ionization and excitation effects as alpha and beta contamination signatures. The second method through theoretical calculations explored the possibility of alphas going into nuclear reaction with oxygen and...
