What you will do

Medical physicists may do some or all of the following:

  • research and develop new equipment and techniques
  • ensure that medical equipment is used safely and correctly 
  • order medical equipment
  • monitor and test radiation equipment and dosage
  • work with a medical team to create treatment plans for patients 
  • interact with patients as part of their radiation therapy treatment
  • contribute to the design of new medical facilities.

Skills and knowledge

Medical physicists need to have knowledge of:

  • physics as it applies to medicine
  • maths and the scientific method
  • the use of radiation to treat cancer or diagnose disease 
  • anatomy, physiology and radiation biology
  • medical technology and equipment.

Working conditions

Medical physicists:

  • usually work regular business hours, but may also work evenings and weekends 
  • work in hospitals or research departments in universities.

Entry requirements

To become a medical physicist you need to have a relevant undergraduate degree, such as one of the following:

  • Bachelor of Science in Physics (Medical Physics and Imaging Technology)
  • Bachelor of Science in Physics
  • Bachelor of Engineering with a strong maths and physics component.

You then enter specialist training and work experience, involving:

  • a Masters of Science in Medical Physics
  • a five-year clinical Training, Education and Accreditation Programme (TEAP), done in conjunction with the Master's degree and specialising in one of three areas, radiation oncology medical physics, diagnostic imaging medical physics or nuclear medicine physics
  • accreditation with the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM).

Secondary education

NCEA Level 3 is required to enter tertiary training. Useful subjects include biology, chemistry, digital technologies, maths, physics, and construction and mechanical technologies.

Personal requirements

Medical physicists need to be:

  • skilled at research, and at analysing and interpreting research results
  • accurate, with an eye for detail
  • well organised
  • good at communicating
  • good at solving problems
  • persistent and patient
  • able to work well independently and as part of a team.

Useful experience

Useful experience for medical physicists includes:

  • any scientific research work
  • work with medical equipment or electronics
  • engineering work
  • computer programming and coding. 

Physical requirements

Medical physicists need to have good eyesight (with or without corrective lenses).

What are the chances of getting a job?

Strong demand for medical physicists

Chances of getting a job as a qualified medical physicist are good due to:

  • an ageing population with more health problems
  • not enough people training as medical physicists to meet demand
  • an ageing workforce, especially in diagnostic imaging
  • a high turnover, as medical physicists often leave to work overseas for better pay.

Medical physicist appears on Immigration New Zealand's long-term skill shortage list. This means the Government is actively encouraging skilled medical physicists from overseas to work in New Zealand.

According to the Census, 144 medical physicists worked in New Zealand in 2018.

Competition for entry to specialist training

There is competition for hospital registrar training positions for the specialist medical physicist Masters programme because there are often more applicants than positions available.

You can increase your chances of getting a medical physicist registrar position if you:

  • have consistently good grades in your undergraduate physics (or related) degree
  • have good communication and problem-solving skills
  • get involved in a relevant university summer research project
  • visit a hospital medical physics department
  • attend the annual medical physics conference
  • apply for a scholarship through the ACPSEM NZ branch.

Most medical physicists work in hospitals

Most medical physicists work in oncology departments of public or private hospitals.

Medical physicists may also work for:
  • universities and tertiary institutions (doing research and teaching)
  • research institutes and laboratories 
  • medical equipment manufacturers
  • private companies providing contracting services for imaging quality control or radiation safety advice.

Progression and specialisations

Medical physicists may progress to doing research in their clinical practice or move into management roles.

Medical physicists working in hospitals may specialise in: 

  • treatment planning
  • radiation safety
  • image quality 
  • linear accelerator management.

Medical physicists may also progress to jobs in areas such as: 

  • teaching or research in universities
  • making medical equipment
  • consulting on new equipment and technology to be used in hospitals.
