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.
Alpha radiation is a stream of particles. These are the nuclei of helium  two protons and two neutrons. This means that they have a (relatively) large mass. Alpha particles from a given radioactive decay all have the same energy (of the order of a few MeV).
