A fuel for generation IV nuclear energy system: Isotopic composition and radiation characteristics
This paper reports on an important issue of designing appropriate nuclear fuel of a high-temperature gas-cooled nuclear reactor operating in a thorium-plutonium nuclear fuel cycle. The neutronic calculations for a fuel of ...
Shielding studies on a total-body neutron activation facility
be located
against the neutron source, patient dose during an
analysis is an important concern when using this
technique. Materials and Methods: Gamma-rays
were attenuated without losing the neutron flux or...
An Optimum Landmine Detection System Using Polyethylene Moderator and 241Am-Be as a Neutron Source
In this paper an optimized moderating structure using an 241Am-Be neutron source
for detecting landmines (using the PGNAA method) has been investigated by experiment. The
experimental set up composed of a Pb cylindrical shell enclosing...
Estimation of Absorbed and Effective Doses on the Different Body Organs from Monoenergetic Neutron Source (10-9MeV-20MeV) Based on the ORNL Analytical Adult Phantom
Every year too many people are treated with radiation therapy and nuclear medicine all over the world. Neutron sources are used for many applications, especially in medicine such as: neutron therapy and neutron imaging. There is a linear...
Digital neutron-gamma discrimination with scintillators: An innovative approach
and 241Am–Be neutron source, whereas the Fourier method has been used to derive the discrimination characteristic. The results confirm the fast performance and efficiency of proposed method....
Conceptual design for a new heterogeneous 241Am-9Be neutron source assembly using SOURCES4C-MCNPX hybrid simulations
in beryllium medium) were compared to a source of homogeneous americium (or its oxides) and beryllium mixture. The proposed heterogeneous geometry was aimed to provide a neutron source with a variable neutron yield, easy-to-shut down and easy-to-waste process...
Review on Fast Neutron Therapy
brachytherapy is an effective treatment for cervix, prostate, skin and breast cancers and more suitable than radiotherapy for cervix and prostate cancers using a californium-252 neutron source brachytherapy. The required dose to kill the same number...
Gamma Shielding Design Studies on 252Cf and 241Am-Be Neutron Sources
of their high flux and reliable neutron spectrum.
They are cost-effective neutron sources for Prompt Gamma Neutron Activation Analysis
(PGNAA). PGNAA method can be used in medicine for neutron radiography and body chemical...
Improving the moderator geometry of an anti-personnel landmine detection system
The optimum moderating geometry using an 241Am–Be neutron source for detecting landmines has been investigated. The experimental setup composed of a Pb cylindrical shell enclosing the neutron source, embedded in a fixed-size high...
The safety of a landmine detection system using graphite and polyethylene moderator
methods used
for landmine detection. In this paper an optimized
(safe and effective) moderating structure using an
241Am-Be neutron source for detecting landmines has
been investigated by experiment and MCNP...
