Variations of gamma radiation spectra during precipitations

Absorption spectra variations of EBT radiochromic film from radiation exposure.

Gafchromic EBT radiochromic film is one of the newest radiation-induced auto-developing x-ray analysis films available for therapeutic radiation dosimetry in radiotherapy applications. The spectral absorption properties in the visible wavelengths have been investigated and results show two main peaks in absorption located at 636 nm and 585 nm. These absorption peaks are different to many other ...

X-Radiation and Gamma Radiation

Ionizing radiation is electromagnetic radiation that has sufficient energy to remove electrons from atoms. Ionization results in the production of negatively charged free electrons and positively charged ionized atoms. Ionizing radiation can be classified into two categories: photons (X-radiation and gamma radiation) and particles (alpha and beta particles and neutrons). Five types or sources o...

Shielding of Gamma Radiation

In the discussion that follows, we assume that gamma rays are the radiation of interest. The principles discussed also apply to monoenergetic x rays; in many cases of concern in x-ray shielding, however, the photons are produced in the bremsstrahlung process that yields a wide and continuous distribution of photon energies. Specialized shielding approaches have been developed to carry out shiel...

Transverse Spectra of Induced Radiation

Transverse spectra of induced radiation are discussed within the light-cone path integral approach to the LPM effect. The results are applicable in both QED and QCD. Recently the Landau-Pomeranchuk-Migdal (LPM) effect [1, 2] in induced radiation in QED and QCD has attracted much attention (see review by Klein [3] and references therein). Understanding the LPM effect in QCD is of great importanc...
