Cosmic radiation External terrestrial and internal radiation
A potential source of ionizing radiation in the dental clinic is the dental x-ray. Dental x-rays are usually conducted to plan for orthodontic treatment, such as braces.

Some applications of americium are:- ionizing source for smoke detectors- component of neutron generators as Am-Be- source in nuclear gauges densitometers- standard source of radiations: gamma, alpha- source for gamma ray radiography- precursor to prepare Cm, Bk, Es, Db, No, Lw- laboratory uses
The main sources of chemical energy are compounds. Some of the common energy sources include gas, food, oil and so many more.
Isotope 225Ac: is used in radiation therapy of cancers. Isotope 227Ac: is used in neutron sources (Ac, Be). Also useful for hydrological study of seas and oceans.

Radiation injuries are caused by ionizing radiation emitted by sources such as the sun, x-ray and other diagnostic machines, tanning beds, and radioactive elements

Common sources of ionizing radiation are alpha particles, beta particles, ultra-violet light, X-rays and gamma rays. Everybody is exposed to small amounts of these radiations every day just from general background radiation or from sunlight.
The film badge measures radiation exposure; an exposed film badge indicates how much radiation a worker has recieved.
Backround radiation is an explosion which occured in space, which consists of radiation comming from all directions in space.
Neutron radiation is as dangerous as any other ionizing radiation, if not more dangerous,as by some sources, it can be as many as ten times more dangerous as other ionizing radiation. It is not directly ionizing radiation, since neutrons do not hold electric charge, but they interact (collide) with nuclei in it's path, creating isotopes, most of the time non-sable, radioactive isotopes. That is why neutron radiation induces a secondary radiation in the material it passes through. The penetration of neutron flux is rather strong, and is not affected by the shield density, as is the case with gamma radiation, but rather by a material rich with Hydrogen (deuterium) atoms, since H atoms contain one single proton/neutron, and the collision physics slow down the neutrons in this matter most efficiently. Therefore, heavy water, plexiglass, plastics and similar materials are used as an effective shield in neutron radiation protection.
People exposed to certain pesticides and ionizing radiation have a higher than average chance of developing this disease.

Radioactivity occurs with the breakdown r decay of certain unstable atomic nuclei. This nuclear radiation is dangerous because it has a lot of energy-on the order of millions of electron volts per emitted particle. Because chemical bonds take about 3-4 electron volts to break, this energy is enough to break apart ordinarily stable molecules into smaller, highly reactive fragments-most of which are ions. Thus, nuclear radiation gets the name ionizing radiation.
a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds

Radioactive sources release some form of radiation, in the case of smoke detectors the specific type will be alpha radiation- most likely from americium 241. The alpha radiation is a helium nucleus which is highly ionizing but is fairly safe since it can only travel around about 5cm in the air, the act of a stream of alpha radiation being intercepted by CO2 cuts a circuit and is how the CO2 is detected.
