Special Announcement

SciBooNE moving today: Some roads closed from 12:30-1:00 p.m.

Roads between Road B and Giese Road will be closed today between 12:30 and 1 p.m. while a major component of the SciBooNE detector is moved. View a map of the road closures here.


Fermilab hosts National Mathematics Advisory Panel

Fermilab Director Pier Oddone gives members of the President's National Math Panel a tour of the 15th floor in Wilson Hall.

Fermilab visitors have a variety of reasons to visit, but inspiration doesn't usually top the list. It was, however, one of the reasons behind the visit of President George W. Bush's National Mathematics Advisory Panel last Thursday.

The Panel is made up of 20 expert panelists and five ex-officio members whose goal is to determine ways to improve mathematics education. While Fermilab isn't exactly known as a mathematics hub, its connection to the physical sciences and its' strong academic reputation were reasons that Panel Chair Dr. Larry Faulkner chose Fermilab as a meeting site.

"These meetings occur across the country, they are usually geographically consistent, but we also try to use sites that have symbolic power and high academic standards," said Faulkner, who is also a former URA board member.

The panel, which was created in April of 2006, is scheduled to report its recommendations to President George W. Bush and U.S. Education Secretary Margaret Spellings by February of 2008. The group largely focuses on ways to improve algebra skills, which have been found to correlate with college attendance rates and college graduation rates.

"I think they've already been inspired," Faulkner said about his fellow panelists, halfway through the meeting at Fermilab.

On Thursday evening Fermilab director Pier Oddone gave the panel a tour of the 15th floor, and former director Leon Lederman gave a dinner presentation at Chez Leon. The panelists met at Illinois Math and Science Academy in Aurora (IMSA) on Friday.

SciBooNE gets ready to move

A crane lifts the carefully wrapped SciBar detector out of the CDF assembly pit, where the detector was put together in the last few months. The SciBar detector is the second component of the new SciBooNe experiment and will be moved into place on Wednesday. The experiment's first component, the Muon Range Detector, will be lowered into the new SciBooNE building at 2 p.m. this afternoon. Employees can watch the move on a live webcam here.

Dwarf stars emit powerful pulse

A class of "failed" star called a brown dwarf emits beams of radiation that are thousands of times brighter than any released by the Sun.

The brown dwarfs are behaving like an altogether different and exotic cosmic object called a pulsar.

Pulsars are rotating neutron stars that emit a flashing radio signal.

When the rotating beams sweep Earth, astronomers detect the radio pulse, which has been likened to the rotating beacon of a lighthouse.

Pulsars are created when a massive star explodes in a supernova and its core collapses into a rapidly spinning neutron star.

Safety Tip of the Week

Precautions after treatment with radioactive isotopes

Radiological treatments, such as the use of radioisotopes to scan lungs for a pulmonary embolism, might interfere with your work at Fermilab. Image courtesy of the Radiopharmaceutical Image Library.

Medical procedures involving radioactive isotopes are more common these days. If a Fermilab employee receives this type of treatment, some precautions might be necessary when the person returns to work.

In nuclear medicine, radioactive isotopes are administered to a patient via injection, inhalation or swallowing. Based on its chemical properties, the material accumulates in specific body parts. For example, Technetium-99 is used in 80 percent of diagnostic procedures for a variety of organs. Thallium-201 is the isotope of choice to assess coronary artery disease. Idoine-131 allows for the treatment of thyroid cancer and other diseases.

After a radiological procedure, the patient is a low-level radiation source for a few hours or days. This can present problems at the workplace. Fermilab's Radiological Control Manual addresses what you should do. Here are some points to keep in mind.

Here are some points to keep in mind:

  • Contact the Medical Department or Area RSO. TThey can provide advice and guidelines.
  • Don't wear a dosimetry badge. Medical radiation should not be part of your occupational radiation record. Until the radiation from your body dissipates, stay out of areas that require a dosimetry badge.
  • Co-workers exposed? Ask your RSO whether the radioactive material in your body presents an exposure problem for nearby co-workers.
  • Radiation instruments affected? Ask your RSO about the potential for interference with radiation measurements.
  • No body fluids in trash. In the hours and days after your nuclear medicine treatment, tissues and napkins containing your body fluids should be disposed of at home. Fermilab's trash is surveyed for radiation before it is picked up, and your trash could cause some confusion.

For more information, read Article 962 of Fermilab's Radiological Control Manual.
