Sum-peak method with two NaI(Tl) crystals: 68(Ge+Ga) standardization

Brazilian Journal of Radiation Sciences, 2019
A 68(Ge+Ga) commercial solution has been standardized in LNMRI in Brazil, by sum-peak method, in which a 3”x3” NaI(Tl) gamma-ray detector is positioned at the top of a well-type 5”x5” NaI(Tl) gamma-ray detector, resulting in a set up approximately  4p ...

Ethics and radiation protection [PDF]

Journal of Radiological Protection, 2007
Some of the major problems in radiation protection are closely connected to issues that have a long, independent tradition in moral philosophy. This contribution focuses on two of these issues. One is the relationship between the protection of individuals and optimisation on the collective level, and the other is the relative valuation of future versus

Radiation dose and protection [PDF]

Canadian Medical Association Journal, 2011
All studies should involve the minimum amount of radiation required to provide the required information. Children have an increased risk from radiation exposure because of a longer expected lifespan and increased tissue radiosensitivity.
