Correction factor for hair analysis by PIXE
Description
The application of the Particle Induced X-ray Emission (PIXE) technique to analyse quantitatively the elemental composition of hair specimens brings about some difficulties in the interpretation of the data. The present paper proposes a correction factor to account for the effects of energy loss of the incident particle with penetration depth, and x-ray self-absorption when a particular geometrical distribution of elements in hair is assumed for calculational purposes. The correction factor has been applied to the analysis of hair contents Zn, Cu and Ca as a function of the energy of the incident particle.(Author)

Propoe-se um fator de correcao para levar em consideracao os efeitos de perda de energia da particula incidente e da absorcao de raios-X quando e feita a analise elementar de cabelo pelo metodo PIXE (Particle Induced X-ray Emission). A dependencia em energia do numero de raios-X caracteristicos dos elementos Ca, Cu e Zn, produzido quando uma amostra de cabelo e irradiada com protons com energia na faixa de 1,5 a 3,5 MeV e determinada, sendo comparada com os resultados experimentais obtidos com o acelerador Van de Graaff da PUC/RJ.(Autor)Files
