Expert Cautions On Effects Of Radition

A consultant in Nuclear Medicine and Radiation has said that although frequent exposure by humans to radiation can be hazardous, it is also beneficial.

“Frequent exposure of radiation could cause body cells to become cancerous but at the same time a calculated high dose of radiation can also destroy cancer cells, Dr Jawa Mohammed said.

According to Mohammed, radiation is a form of energy that travels in mass, comprising ionizing and non-ionizing radiation.

Mohammed explained that the ionizing radiation in x-rays and Gama rays could cause tissue damage to the body while non-ionizing radiations in bulbs have less effect on tissues.

He stated that radiation exposure could be medical and non-medical, while x-rays and Gama rays are examples of medical radiation.

“Non-medical radiation is emitted from instruments such as cell phones, radio waves, television and computer screens,” he said.

The consultant said the amount of radiation penetrating the body at a time might not pose a problem but the frequency and duration of each exposure, adding that a patient who underwent an x-ray for a diagnosis was only exposed to a minimal amount of radiation which would have no effect.

“However, such a person could be affected if exposed to smaller doses over a period of time.

Radiation interacts with water which is the most abundant chemical substance in the body, constituting 97 per cent of the human body.

The interaction is called hydrolysis and can cause mutation of cells or genes, resulting in cancer.

Mohammed stated that such exposure could interfere with the genes of women and adversely affect their ability to reproduce, leading to congenital abnormalities.

He said that radiation also has a huge benefit in diagnosis, therapy and treatment of various diseases.

“If the exact position of the cancer is calculated and the right dose of radiation is administered, the cancer can be destroyed while preserving the surrounding tissues of the patient. “

He added that scanning machines used on expectant mothers is low in radiation, having little effect on both the mother and the baby.

The Lagos State Government on Saturday refuted an online media report claiming that the state had resumed the monthly environmental sanitation exercise.

The Commissioner for the Environment and Water Resources, Mr Tokunbo Wahab, said no categorical statement had been made regarding the commencement date of the exercise.

Wahab explained that what he told newsmen after a project inspection tour last Sunday was that engagements with relevant stakeholders were still ongoing.

He said the state government had planned to begin with a sensitisation programme last week, but was constrained by logistics issues.

“The truth is, we were meant to start with a sensitisation programme last week, but we had a logistics issue. We need to find a day that is acceptable to all stakeholders,” he said.

He expressed optimism that the exercise might return very soon, adding that the official date would be communicated by the Governor, Mr. Babajide Sanwo-Olu.

The commissioner urged law-abiding residents to continue their lawful activities without hindrance, assuring them that adequate notice would be given before the exercise was reintroduced.

The monthly environmental sanitation, previously held on the last Saturday of every month between 7.00 a.m. and 10.00 a.m., was suspended in November 2016 following a legal pronouncement restricting movement during the exercise.

However, renewed waste management challenges, including clogged drainage channels and indiscriminate refuse disposal, have sparked calls from residents for its reinstatement.

Ministry Of Environment To Validate A Landmark Policy To Advance Nigeria’s Economy

The Federal Ministry of Environment last Thursday convened key stakeholders in Abuja to validate a landmark policy brief aimed at tackling marine litter to advance Nigeria’s transition to a circular economy.

Mrs Falmata Bukar-Kolo, the Deputy Director, Solid Waste Management and Technology Division in the ministry, warned that plastic pollution poses serious risks to aquatic ecosystems and public health.

She stated that microplastics have already entered the food chain through fish consumption, while clogged waterways, soil contamination, and greenhouse gas emissions from burning plastics are worsening the environmental crisis.

Bukar-Kolo said that plastics, though widely used, are non-biodegradable and persist in the environment for years.

She called for improved waste management systems, stronger enforcement of environmental regulations, and behavioural change amongst citizens and businesses.

Mr Clem Ugorji, Regional Coordinator of PROTEGO, emphasised on the urgency of action, saying Nigeria’s marine litter crisis carries environmental, economic, and reputational costs.

He expressed optimism that the 2025 to 2040 roadmap endorsed at the workshop would shift the country from prolonged dialogue to concrete implementation.

The event was organised in collaboration with PROTEGO (Prevention of Marine Litter in the Gulf of Guinea).

Discussions centred on a draft policy input paper titled “Policies, Institutional Set-up and Financing of Marine Litter Prevention in Nigeria,”.

These seeks to present insightful analysis and a set of recommendations to address the structural and financing gaps that have long hindered effective waste management, particularly plastic leakage from inland communities and waterways into the Atlantic Ocean.

The PROTEGO initiative is supported by the German Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection and led by adelphi, with implementation in Nigeria by WASTE Africa and the Nigeria Climate Innovation Centre (NCIC).

The policy brief is a key delivery for one of the programme’s four impact areas – building capacities of public stakeholders.
