Cancer risks from chest radiography of young adults: A pilot study at a health facility in South West Nigeria.

The recommendation of chest radiography for school admission and employment purposes should be discouraged due to the risks of radiation especially cancer induction. It is therefore imperative to keep diagnostic radiation doses as low as possible. This dataset presents the entrance surface dose, effective dose, bone marrow dose, breast dose, lung dose and the incidence cancer risks from chest radiography of 40 young adult females.

Optimization of dual slot antenna using floating metallic sleeve for microwave ablation.

Backward heating reduction is vital in power distribution optimization in microwave thermal ablation. In this study, we optimized dual slot antenna to yield reduction in backward heating pattern along the antenna shaft with the application of floating metallic sleeve. Finite element methods were used to generate the electromagnetic (EM) field and thermal distribution in liver tissue.

Potential health risks due to telecommunications radiofrequency radiation exposures in Lagos State Nigeria.

Background: The global system mobile telecommunications system (GSM) which was recently introduced in Nigeria is now being used by over 40 million people in Nigeria. The use of GSM is accompanied with exposure of the users to radiofrequency radiation (RFR), which if significant, may produce health hazards. This is the reason why many relevant national and international organizations recommended exposure limits to RFR and why it is made compulsory for GSM handsets to indicate the maximum power output as a guide to potential consumers.

Assessment of pre-operational radiological conditions at the Linac Centre of the Lagos University Teaching Hospital, Nigeria.

Background: The Lagos University Teaching Hospital, Nigeria has acquired a 6 - 15 MeV ELEKTA linear accelerator for clinical teletherapy. The 15 MeV is a sufficient energy to activate photonuclear interactions of the type (h(nu), n) and (h(nu), e), in some materials found within the locality, thereby enhancing the background radiation exposure levels in the environments.

Objective: The objective of this study is to conduct a pre-operational assessment of the radiological conditions of the new LINAC Centre and its environments which is required for future uses in the assessment of the environmental impacts due to the applications of the facility.
