Prior to 1980, activities involving radium-226 and most other radionuclides ceased, and tritium remained as the only radionuclide used in the manufacturing of self-illuminating watch dials, instruments, and other products.
Purolite, a manufacturer of ion exchange, catalyst, adsorbent and specialty resins, has announced it has achieved non-detect levels on all of the 62 radionuclides in the coolant water at Tokyo Electric Power Company (TEPCO) Fukushima Daiichi Nuclear Station in Japan.
Exposure to radionuclides, such as iodine-131 and cesium-137, increases the incidence of cancer.
In general, majority of the radionuclides used in PET imaging are produced by cyclotrons either on site or at a site near the scanner.
The point is that when a medical laboratory gets a call for imaging with radionuclides that have half-lives in the seconds or minutes, they can reach for a parent material with long shelf life that they can modify, rather than having to cook up a new batch from scratch with a nuclear reactor in the basement.
dagger]) Bioassays are analytical technologies that detect the type and amount of radionuclides in a urine sample to determine the amount of internal radionuclide contamination that a person has received during a radiological or nuclear incident.
A smart processor examines each photon as it arrives and decides whether a detected radionuclide is accepted or not based on selected parameters.
These investigations have revealed low levels of a variety of radionuclides in water, sediments, and biota (McLean & Long 1978, McLean et al.
They produce mostly exotic and less commonly used radionuclides.
Yet the physical properties of many building materials--and of the radioactive isotopes, or radionuclides, that would land on them--complicate the task of thoroughly removing the contamination.
