SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing.
Radiation Physics and Chemistry aims to publish articles with significance to an international audience, containing substantial novelty and contributions to science. We expect that articles present new insight or hypothesis testing, that they focus on radiation effects or applications of ionizing radiation, provide uncertainties and statistical analysis where relevant, and present their findings in context with discussion of past and recent literature. The editors reserve the right to reject, with or without external review, articles which do not meet these criteria. This could include articles which are very similar to previous publications, except that target substrates, materials, analyzed sites or experimental methods have been changed.
A fuller though not exhaustive list of topics that are considered for publication include:
Fundamental processes in radiation physics
• Interaction mechanisms for example scattering and absorption of photon and particle radiations
• Attenuation coefficients
• X-ray fluorescence
• Cherenkov effect
• Effects of periodic structures (Bragg diffraction, channelling, parametric x-radiation, etc)
• Mathematical methods in radiation physics, reference data
Radiation sources and detectors
• Accelerator and radionuclide spectra and other properties
• Radiation fields from point and extended sources
• Detector response functions
• Basic physics of Dosimetry
• Radiation transport
• Buildup factors
• Ionizing radiation induced ionic and radical reactions
• Kinetics and mechanism of radiolysis reactions
• Pulse radiolysis technique and measurements
• Nanoparticle production by ionizing radiation
• Radiation induced chain reactions, polymerization
• Irradiation effects on polymers
• Dose and dose rate effects
• LET effects on chemical reactions
• Pollutant removal by ionizing radiation
• Computational models on radiation chemical reactions
Papers on photochemistry, microwave chemistry and thermochemistry are believed to belong to the scope of RPC only if they have strong relevance to radiation chemistry. EPR papers will only be considered for publication when the method is used for clarifying radiation chemical processes, e.g. by determining the nature of the transient intermediates. Radiochemistry papers such as tracer technique, radon or other radionuclide measurements, isotopic constitutions fall outside the scope of the journal.
