A high level of radioactive contamination still persists today.

It constitutes most of the radioactivity still left from the Chernobyl accident.

By following the precautions described in this document, the radiation hazards involved with handling decedents containing residual radioactivity are minimal.

These fission products account for the persistent radioactivity in bomb debris, because many of the atoms have half-lives measured in days, months, or years.

Finally, the same department has scanned the entire reactor building to trace any residual radioactivity and, if necessary, safely remove it.

During the 1960's the English conducted atomic bomb testing, at only a few kilometres from the site, and today the site is not accessible due to strong residual radiation.

evidence to indicate that most of the area has little or no residual radioactivity directly attributed to

Tim had to endure another week of isolation after being discharged from the hospital in order to protect his wife and young children from any residual radiation.

Based on information collected during the missions and subsequent research, there is sufficient evidence to indicate that most of the area has little or no residual radioactivity directly attributed to nuclear tests in Kazakhstan.

The food never comes into contact with radioactive material, and the irradiation both maintains the quality and increases the safety of the food while leaving no residual radioactivity.

During the 1960's the English conducted atomic bomb testing, at only a few kilometres from the site, and today the site is not accessible due to strong residual radiation.
