چکیده

An attempt has been made in the work to assess radiological dose due to the deposition of 131 I, 132 I, 133 I, 134 I, and 135 I on ground, vegetation, milk and meat considering a hypothetical accident of TRIGA Mark-II research reactor at AERE, Savar, Bangladesh. Contribution of dose from ingestion of vegetation due to 131 I has been found to be dominant (62.96%). Also found that contribution of 132 I from immersion is higher (53.67%) and contribution of 133 I in meat is higher (45.64%). The contribution due to 134 I in both from immersion (46.13%) and from ground deposition (47.19%) was dominant while the contribution of 135 I from ground deposition (30.11%), inhalation (26.77%) and immersion (25.92%) were higher. Final result says that the vegetation is the dominant contributor (66.91%) for iodine.

TRIGA Mark-II Research Reactor

The present work gives a methodology for assessing radiological concentration of I, I, I, I, and I due to a hypothetical accident of TRIGA Mark-II research Reactor at AERE, Savar, Bangladesh. The concentrations were estimated through different pathways like ingestion of vegetation, milk, and meat from air and ground deposition. The maximum air concentrations for all 16 directions were found at ...

Comparison of Absorbed Fraction of Gamma and Beta Rays of I-124 and I-131radio-Isotopes in Thyroid Gland with Monte Carlo Simulation

I131 is a famous radio-iodine isotope in use for diagnosis and treatment of hyper functioning and cancerous thyroid gland. It is a nuclear reactor product; however nuclear reactor may be unavailable in some areas. Replacement by I-124 may be possible, another iodine isotope producible by cyclotron; a system more available than reactor. Here absorbed fraction of Gamma and Beta rays of...

Comparison of I-131, I-123 Absorbed Dose and Tc-99m in Thyroid Scanning Using MCNP Code in ORNL-MIRD Phantom

Introduction: Thyroid cancer is at the ninth from ten of common malignant cancer. A man has higher risk to get Thyroid cancer that a woman has. This organ is lain near human neck. The use of radioactive I-131, I-123 and Tc-99m for diagnosis of thyroid cancer has a risk where other organs around Thyroid will accept dose of radiation. One of the risks is large dose which is accep...
