Pengukuran Dosis Eksternal Yang Diterima Oleh Mahasiswa Praktikum Teknik Radiografi di Laboratorium Radiologi Universitas Baiturrahmah Padang

Abstract

The utilization of ionizing radiation in the form of X-rays in addition to providing benefits to the medical world also has the potential to have a detrimental effect on workers, patients and, society. Radiation protection is a very important aspect of controlling this adverse effect. Every utilization of ionizing radiation must have endeavored so that the reception of radiation doses by radiation workers is always as low as possible so that the prescribed dose limit (NBD) value is not exceeded. NBD for apprentices and students who are as low as 18 years old, who are carrying out training or practical work, or who because of their educational needs are forced to use a source of ionizing radiation, the same as the NBD that applies to radiation workers. Dose limit values for radiation workers must not exceed 20 mSv (twenty millisieverts) per year on average for five consecutive years. Determination of the external radiation dose received by practicum students at the Baiturrahmah University Radiology Laboratory aims to calculate how much the external radiation dose received by students during carrying out one course. Based on the results of the study found that the measurement of external radiation dose received by the student is 0 or there is no scattering radiation received by students, this is because at the time of exposure they are in the correct position that is behind the control panel wall that has been coated with Lead (Pb).
