Work environment

Work in this occupation is typically performed in a structured environment, such as an office or a university. Work may also be conducted either outdoors or in observatories.

Hazards exist as a part of carrying out various job duties within these occupations. For example, exposure to ionizing radiation, such as X-rays and radioactive substances, or non-ionizing radiation, such as radio frequencies and infrared, ultraviolet or visible light, may affect health adversely.  Use of safety precautions and procedures minimize these risks.

Career paths and resources

Career paths

Physicists may work closely with and perform some of the duties of engineers. Also, mobility between specializations within physics, within astronomy and other fields of science, such as meteorology and geophysics, is possible with experience. Progression to management positions is possible with experience.
