| dc.description | When a cost???benefit analysis is applied to the optimization of practices involving radiation protection, the alpha value is used
to determine the amount of money required to be invested in a practice to minimize radiation doses to acceptable levels. The
alpha value is often linked to the gross domestic product (GDP) per capita, so the monetary reference value of person-Sievert
can often be different in each country. Evaluation of the alpha value in Brazil was performed in 1993 and 2000 making use of
the procedure advised by ICRP to produce projections up to 2015 and subsequently in 2004 by using the procedure recommended
by the IAEA. This paper, in response to the social and economic situation in Brazil, calculates the alpha value and
compares it with the projections of the 1993 and 2000 papers and includes a dollar correction to take account of the differences
in the purchasing power from that time. This procedure illustrates the significant gap of value in use and that the actual
value should be two to three times higher. By GDP per capita, the authors could calculate the alpha value updated to various
countries including the European Union and compare them with the official value currently in use. In conclusion, it is believed
that all countries that adopt an alpha value should upgrade it to the present day. | |
