Answer:
Photon radiation
A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).
The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.
E) be more susceptible to disease and famine

<u>a. Earth quakes</u> are common.
<h2>
Explanation:</h2>
"Ring of Fire" is a significant region in the bowl of Pacific Ocean where numerous earthquakes and volcanic ejections happen. In an enormous 40,000 km horseshoe shape, it is related to an about nonstop arrangement of maritime channels, volcanic circular segments, and volcanic belts and plate developments. It has 452 volcanoes.
About 90% of the world's tremors and about 81% of the world's biggest seismic tremors happen along the "Ring of Fire". The Ring of Fire is an immediate aftereffect of plate tectonics: the development and impacts of lithospheric plates, particularly subduction in the northern segment.
