The development of number of medical physicists in the hospitals and the number of inhabitants in Finland at 10-20 year intervals (the first medical physicist position was established in 1937) are shown in the Table below.
| Year | 1950 | 1970 | 1990 | 2010 | 2020 |
| Number of physicists | 2 | 21 | 66 | 99 | 140 |
| Inhabitants (millions) | 3.9 | 4.6 | 5.0 | 5.3 | 5.5 |
| Physicists/100 000 inh | 0.05 | 0.46 | 1.36 | 1.87 | 2.55 |
In Finland the Qualified Medical Physicists work also in fields, where ionizing radiation is not used, and all Qualified Medical Physicists do not work as Medical Physics Experts. This is different from many other European countries.
| Radiation Therapy | 39 % |
| Nucl. Med. And Clin Physiol. | 25 % |
| Radiology | 23 % |
| Clinical Neurophysiology | 14 % |
