INTRODUCTION
Radiation is used every day in the UK, it is used for different purposes such as medical, industrial, research and communication.
Some of these can potentially be harmful when exposed, which must be controlled effectively. The health and safety Executive (HSE)
regulates the work which exposes radiation to workers, the public or both.
Health and safety measurements in scientific organisation comply with legislation, by having laws and rules put in place for
companies to follow; different institutions will have different rules to follow under the HSE. The HSE helps regulate workplaces and
prevents safety concerns and death from occurring. Laws state that organisations must have protective measures that will help
prevent so to Plan, Assess, organise, control, and monitor employees, patients and others who could also be impacted is a necessity.
All Employees should be given special training (such as how to operate machinery to carry out certain treatments on patient, patient
confidentiality and how to treat patient and health and safety requirement of equipment and surgery rooms) that is required to
adapt to the workplace and should be aware of any health and safety risks that could occur during activities if not followed
accordingly there will be a cost for both organisation and individuals; include fines, imprisonment, and disqualification.

RISK ASSESSMENT
Managing risk comes under the Management of Health and safety at Work Regulations 1999, and Standard operating procedure
(SOP) as an employer you are required to by law. (www.hse.gov.uk, n.d.) [1] A risk assessment is a legal requirement which a
workplace must carry out. It should be done regularly, due to the change in nature of workplace from time to time or new hazards
could be raised which were not seen before. This is important as new additional training maybe required to improve risk. The term
‘risk’ means the degree of likelihood that harm will be caused by a potential hazard.
Under the management of Health and safety at Work Regulations 1999, employers are required to undertake suitable and sufficient
Risk assessments to identify risks and hazards relating to the health and safety of operators and patients in the workplace and put in
place additional measures to manage and reduce the likelihood of harm.
WHAT IS CONSIDERED IN RISK?
Possible accidents situations and their likelihood and potential safety.
The consequences of possible failures of control measures.

Patients with medical implants may not be allowed to have an MRI scan due to an implant being able to
