Shielding commissioning factors in nuclear medicine facilities

Journal of Radiological Protection, 2020
This article reviews the essential considerations in planning and designing nuclear medicine departments. There are four proposed categories to consider as 'shielding commissioning factors' (SCF). The first SCF: 'Patient flow optimisation and workload' emphasises the importance of carefully considering patient flow in the departmental design, which ...

Atomic Susceptibilities and Shielding Factors

Physical Review, 1969
A calculation of electric and magnetic susceptibilities and shielding factors for closed-shell atomic systems based on relativistic Hartree-Fock-Slater (RHFS) electron theory is presented. Numerical results are given for the electric dipole and quadrupole, and for the magnetic dipole and octupole cases for closed-shell atoms and ions from $Z=2$ to $Z ...

Frequency-dependent dipole shielding factors

Journal of Physics B: Atomic and Molecular Physics, 1969
A frequency-dependent dipole shielding factor βinfinity(ω) is defined as the coefficient of proportionality between the electric-dipole induced field and a uniform external electric field, at the nucleus, when the external field varies sinusoidally with time and with circular frequency ω. From oscillator sum rules it is shown that βinfinity(ω) = N/Z0 +

Simplified equation for the shielding factor of multiple shielding conductors

Electrical Engineering in Japan, 1976
Electromagnetic interference problems have become increasingly important due to the development of high-voltage bulk power transmission lines and the expansion of ac railway systems. The shielding factor of the shielding conductor is very important in calculating the electromagnetically induced interference voltage.

Estimation of Shielding Factors for Linear Accelerators*

Health Physics, 2002
There have been a number of persons who have estimated that the use of multi-leaf collimation and IMRT techniques increase the workload in treatment rooms to the extent that assumptions used in shielding calculations should reflect these increased workloads.

Electronic Polarizabilities and Sternheimer Shielding Factors

Physical Review, 1963
A new method is developed for determining the distortions (polarizabilities) induced in electronic distributions by valence electrons and/or crystalline fields and their effect (expressed as Sternheimer shielding factors) on magnetic and electric hyperfine interactions.

Shielding Factors and External Dose Evaluation

Radiation Protection Dosimetry, 1987
The kerma in typical European houses in urban and suburban environments due to the gamma radiation from the contamination of different deposition areas such as lawns, trees, windows, walls, roofs, paved areas, light-shafts and internal surfaces has been calculated by extensive Monte Carlo simulations.
