"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.
Study Type
OBSERVATIONAL
Enrollment
44
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. Data will be collected using a structured questionnaire and blood tests for thyroid hormones (TSH, T3, T4) to assess thyroid function. Blood analysis will be conducted using CLIA or ELISA methods. The aim is to detect any association between low-dose radiation exposure and thyroid dysfunction.

thyroid function assessment
Thyroid function is assessed through blood tests, primarily measuring TSH (Thyroid Stimulating Hormone), T4 (Thyroxine), and sometimes T3 (Triiodothyronine) levels. Abnormal levels of these hormones can indicate an underactive (hypothyroidism) or overactive (hyperthyroidism) thyroid. Normal Ranges (approximate): TSH: 0.4 - 4.0 mIU/L Free T4: 0.7 - 1.9 ng/dL Total T4: 5.0 - 12.0 μg/dL Total T3: 80 - 220 ng/dL
Time frame: 12 Months
