1) Regarding Barium as a contrast agent
One answer only.
Gastrografin (Sodium and meglumine diatrizoate) added to barium during a small bowel study increases the transit time of barium through the small bowel
A narrow spectrum of sizes of barium sulphate particles is needed to demonstrate the areae gastricae
A lower density of Barium is used for double contrast studies than is used for single contrast studies of the stomach
A barium suspension of 12%w/v is used to opacify the gastrointestinal tract during CT scans
Barium has been used intravascula...

• X- and g -rays are called sparsely ionizing because along the tracks of the electrons set in motion, primary ionizing events are well separated in space.
• Alpha-particles and neutrons are densely ionizing because the tracks consist of dense columns of ionization.
X-rays, gamma rays, electrons, and protons are all low LET forms of radiation in that their density of ionization is sparse. In general, they penetrate tissues deeply and result in less intracellular radiation injury. High LET forms of radiation, such as heavy nuclear particles (e.g. fast neutrons), penetrate tissues less deeply and cause more radiation injury to biologic material.
