Seagulls have always been the greatest enemy for drones. Today our Mavic pro came face to face with a seagull and luckily it swiftly dodged the drone. It was soo quick!

Medical diagnostic procedures used to define and diagnose medical conditions are currently the greatest manmade source of ionizing radiation exposure to the general population. However, even these sources are generally quite limited compared to the general background radiation on Earth. The risks and benefits of radiation exposure due to medical imaging and other sources must be clearly defined for clinicians and their patients. This article is a general overview for the medical practitioner, who should understand the fundamentals of medical ionizing radiation and the general associated risks. This article also acquaints the practitioner with relative doses of common radiographic procedures as well as natural background radiation. The use of ionizing radiation in medicine began with the discovery of x-rays by Roentgen in 1895. Ionizing radiation is the portion of the electromagnetic spectrum with sufficient energy to pass through matter and physically dislodge orbital electrons to form ions. These ions, in turn, can produce biological changes when introduced into tissue. Ionizing radiation can exist in 2 forms: as an electromagnetic wave, such as an x-ray or gamma ray, or as a particle, in the form of an alpha or beta particle, neutron, or proton. X-rays are machine-generated, whereas gamma rays are electromagnetic waves that are emitted from the nucleus of an unstable atom. Different forms of ionizing radiation have differing abilities to generate biologic damage. The order of ionization effect of these forms can be found in Table 1 below. A clear understanding of the measurement units of radiation and radioactivity is required to better communicate with colleagues or patients. Different units are used to describe radioactivity by energy (erg), decay activity rate (curie [Ci] or becquerel [Bq]), effect in air (roentgen [R]), ability to be absorbed (radiation-absorbed dose [rad] or gray [Gy]), or biologic effect (roentgen equivalent man [rem] or sievert [Sv]).
