A review of international and developed practices of medical physics from a legislative and regulatory point of view and its applicability and comparison with Pakistan.

The importance of the medical physics profession and medical physicists is widely recognized by the international bodies like ILO, IAEA, EC, etc. The description of a medical physicist's qualification framework, their role and responsibilities have been addressed in the legislative and regulatory frameworks of developed countries like the USA (in 10CFR) and the EC (EC RP 174) and less comprehensively in developing counties like Pakistan. AFOMP has contributed positively in various regulatory and policy matters regarding the medical physics practices in Asian countries.

Radiofrequency radiations induced genotoxic and carcinogenic effects on chickpea ( L.) root tip cells.

Present study was under taken to predict the possible DNA damages (genotoxicity) and carcinogenicity caused by radiofrequency radiations (RF) to living tissue. Dry seeds of chickpea were treated with GSM cell phone (900 MHz) and laptop (3.31 GHz) as RF source for 24 and 48 h.

Dose measurement of cobalt-60 radiotherapy beams in treatment fields.

Background: Radiation-therapy is a complex process with multiple steps, each of which has an impact on the quality of treatment. Accurate dosimetry is a critical step during the radiotherapy of cancer patients.The aim of the present study was to measure and evaluate the doses of two cobalt- 60 (60Co) teletherapy units GWXJ80 of NPIC China and Theratron 780 of AECL Canada at various points within fields for different field sizes.
