Photons, interaction with matter

Charged Particle and Photon Interactions with Matter... 

It is our pleasure and privilege to thank our friends and colleagues all over the world who have contributed to our understanding of the high-energy charged particle and photon interactions with matter. 

Figure 17.14 Summary of the relative importance of the three mechanisms by which photons interact with matter. The curves indicate the locations in the atomic number-photon energy plane at which the cross section for Compton scattering is equal to that for photoelectric absorption, left side, or is equal to that for pair production, right side.

In addition to the process (2), positronium can also be generated by photons interacting with matter [14,44,48,49].

Recent Trends presents a picture of radiation chemistry as a vibrant field of international venue, still addressing fundamental challenges as it continues to grow into its second century. This image is reinforced, and both broadened and deepened, by a number of edited volumes Rndintion Chemistry Present Status and Future Trends — Jonah and Rao (2001) Char ed Particle and Photon Interactions with Matter — Mozumder and Hatano (2004) Radiation Chemistry From Basics to Applications in Material and Life Sciences— Belloni et al. (2008) which have appeared within the last few years. A clear articulation of prospects for future development was also presented at the recent visionary meeting Radiation Chemistry in the 21st Century held at Notre Dame in July, 2009.

Filled polymers play a role in primary and secondary protection against y-radiation. The photons interact with matter by photoelectric absorption and Rayleigh scattering. For primary partitions which separate an unshielded source from its surroundings, lead bricks or concrete blocks are used. For the secondary partitions which protect personnel from radiation, a protective shield or vest can be made by incorporating metal particles or lead oxide in rubber or plastic. Such shields are used by physicians and dentists or their patients to limit exposure to x-rays. The radiation... 

An important quantity in the discussion of photon interaction with matter is the half-value layer (HVL), which is defined as the thickness of the absorber that attenuates an initial photon beam intensity to one-half. The HVL increases with higher energy of the photon and decreases with increasing atomic number of the absorber. Lead is a high atomic number inexpensive metal that has very high absorbing power for 7 radiations providing low HVL values and that is why it is commonly used for radiation protection. The HVL...

In Rayleigh scattering, a photon interacts with matter to alter its direction of motion, but the photon energy is unchanged. 

When photons interact with matter a fixed amount of energy is transferred to the matter, in contrast to the types of radiation discussed in the last section. There are...
