Radiation Protection Pipette Shields

Pipette Shields
These specially designed pipette shields fit snugly on the pipette shaft. This protects the hand during the dispensing sequence and enables the user to dispense safely into small and narrow neck containers. Two types of shields are manufactured which are specifically designed to fit either Gilson or Biohit pipettes.

Beta Protection Products
Beta emissions of 32P, 35S, 3H and 14C can be effectively blocked by using 10mm thick optical acrylic, which is now the accepted standard for shielding beta emissions in biological research. The properties of this acrylic material are ideal for the construction of beta radiation protection products. It is easy to bend, fabricate and machine into a wide range of products. Also, being transparent, the visibility of the working environment is not impaired.

Gamma Protection Products
Protection from gamma emitting isotopes, such as 125I, 133Xe, 57Co, 99mTe, 123I and 67Ga has, until recently, been achieved by lead shielding. This has its obvious disadvantages, being very heavy and non-transparent. However, a new lead containing acrylic co-polymer resin is now readily available. The lead content of the resin is 30% wt/wt and is chemically introduced into the acrylic resin as an organolead salt. This material is transparent with a very light brown tint and it exhibits virtually all the normal chemical and physical properties of conventional acrylic resin. Scie-Plas Limited provide a range of products using 12mm thick lead-acrylic, which is equivalent to 0.5mm thick lead. This range of products effectively blocks gamma emissions from 125I and any gamma emitters of lesser energy. It is NOT suitable for use with more energetic isotopes of iodine. However, a 35mm thick shield is available, which is equivalent to 1.7mm thick lead, which can be used with isotopes of higher energy.

12mm thick lead-acrylic is suitable only for the protection of gamma emissions from 125I and not from other higher energetic isotopes of iodine.Lead or lead-acrylic is not recommended for shielding beta emissions. When a beta particle collides with an atom with a high atomic number, such as lead, a hazardous X-ray-like emission, known as BREMSSTRHBLUNG is generated. To avoid producing significant amounts of bremsstrhblung, use only optical clear acrylic products to shield beta emissions.
Radioactive compounds have been used in research laboratories for many years and the results of this research have benefited mankind considerably. In life science research, radioactive compounds are used in the detection of nucleic acids and proteins as well as in many other techniques such as radioimmunoassay and as tracers in metabolic studies. The most often used isotopes which emit beta () radiation particles are: [32P] phosphorous, [35S] sulphur, [14C] carbon and [3H] tritium. While [125I] iodine, [133Xe] xenon, [57Co] cobalt, [99mTe] technetium, [123I] iodine and [67Ga] gallium, emit gamma (g) particles.
Generally, beta emissions are negatively charged particles (electrons), emitted from the nucleus of an atom. Depending on the particular atom, the energy level of the charged particle will vary. Phosphorous is regarded as having a high energy level of beta radiation particles, being 10 times greater than that of tritium, and which can travel up to seven metres in air. Phosphorous is therefore known as a "hard" emitter of beta radiation, while tritium, sulphur and carbon are regarded as "soft" emitters of beta radiation.
125I is a weak emitter of gamma radiation particles. Gamma emissions are a form of electromagnetic radiation similar to that of light, generated by the nuclear decay of an unstable isotope. They are much more penetrating than beta emissions and can travel very long distances in air.
