While usually transmitted by ticks, haemobartonellosis can also be carried by fleas. The disease targets red blood cells and can range from mild to very severe symptoms. If very severe, haemobartonellosis can cause cats to suffer anemia that results in weight loss and a fast heart rate.
Alpha radiation is a type of energy released when certain radioactive elements decay or break down. For example, uranium and thorium are two radioactive elements found naturally in the earthâs crust.
Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing. Examples of some alpha emitters: radium, radon, uranium, thorium. 2  Most alpha radiation is not able to penetrate human skin. 3  Alpha-emitting materials can be harmful to humans if the materials are inhaled, swallowed, or absorbed through open wounds. 4  A variety of instruments has been designed to measure alpha radiation.
