Biological Effects of Radiation

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...

Fischer Projections

Fischer Projections

Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Newman Projections

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Absorption of Radiation

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

Area of Science:

Medical Physics
Cardiology
Radiology

Background:

Radiation exposure in cardiac catheterization (cath) labs poses risks to patients and staff.
Previous efforts using advanced equipment and general radioprotection measures have reduced exposure.
Further optimization is needed to minimize cumulative radiation doses.

Purpose of the Study:

To evaluate the effectiveness of modified protocols and pelvic shielding in reducing radiation exposure during cardiac catheterization procedures.
To quantify the reduction in radiation dose for patients, cardiologists, and nurses.

Main Methods:

A pilot quality improvement project was conducted over three 8-week periods.
Baseline radiation exposure was measured.
Period 2 involved adjusting standard incidences for coronarography and frame rate.
Period 3 incorporated a pelvic shield for patients.

Main Results:

A significant 37% reduction in patient radiation exposure was achieved.
Cardiologists and nurses experienced substantial reductions of 53% and 62%, respectively.
These reductions were observed despite existing radiation-saving measures.

Conclusions:

Implementing protocol adjustments and pelvic shielding can further decrease radiation exposure in cath labs.
Significant dose reduction is achievable for both patients and healthcare professionals.
This approach offers a viable strategy for enhancing radiation safety in interventional cardiology.
