Biological Effects of Radiation02:59

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...

Absorption of Radiation

The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Methods for Studying Drug Absorption: In situ

In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

Area of Science:

  • Biomedical Engineering
  • Radio Frequency Engineering
  • Human Body Modeling

Background:

  • Internal biomedical telemetry systems require understanding radio frequency (RF) signal attenuation through the human body.
  • Accurate attenuation data is crucial for designing reliable wireless communication for ingested or implanted devices.

Purpose of the Study:

  • To estimate the attenuation of the human body trunk for RF signals from 100 MHz to 6 GHz.
  • To identify suitable radio frequency bands for biomedical telemetry systems based on attenuation characteristics.

Main Methods:

  • A simplified experimental model of the human body trunk was used.
  • The model was filled with distilled water, saline solution, and porcine tissue to measure signal attenuation.
  • Attenuation was measured across a frequency range of 100 MHz to 6 GHz.

Main Results:

  • Saline solution exhibited higher attenuation than water due to increased conductivity.
  • Porcine body tissue showed attenuation values between those of saline and water.
  • Estimated attenuation at Industrial, Scientific, and Medical (ISM) bands (434 MHz, 915 MHz, 2.45 GHz, 5.8 GHz) met safety and sensitivity requirements.

Conclusions:

  • The 915 MHz and 2.45 GHz bands are recommended for wireless links in biomedical telemetry due to component size advantages.
  • The study provides reference attenuation values for an average-sized human body trunk.
  • Attenuation can vary with individual body size and composition, necessitating consideration for specific applications.
