"This study is designed to evaluate the thyroid health of healthcare workers exposed to low-dose ionizing radiation at INMOL Cancer Hospital, Lahore. Specifically, it investigates whether prolonged occupational exposure in radiology and nuclear medicine departments is associated with altered thyroid hormone levels or an increased risk of hypothyroidism. The thyroid gland is highly sensitive to radiation, and existing literature suggests a possible link between occupational exposure and thyroid dysfunction.

A cross-sectional research design will be used over a four-month period. A sample of 44 participants will be selected using purposive sampling from the hospital's radiology and nuclear medicine staff.

Inclusion Criteria:

• Staff members from radiology and nuclear medicine departments who meet both conditions.
• workplace experience exceeding one year
• age between 20 to 40 will be selected for this study.

Exclusion Criteria:

• Employees who have worked less than twelve months
• pregnant participants.

This study will include healthcare professionals from the radiology and nuclear medicine departments at INMOL Cancer Hospital with at least one year of radiation exposure. A total of 44 participants will be selected through purposive sampling.
