The box is available either as a Beta shield fabiciated in standard arcylic material or as a gamma shield fabricated in 12 mm thick lead acrylic corresponding to 0.5 mm lead shielding.

The box comprised an outer box and a solid acrylic insert with machined holes deigned to accept 24 x 1.5ml and 15 x 0.5ml Eppendorf tubes. There is a separate removable recessed lid also made of 12 mm lead acylic

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 copolymer 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 organo-lead 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. We 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.

BETA and GAMMA SHIELDS

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 (ß) radiation particles are: [³²P] phosphorous, [³⁵S] sulfur, [¹⁴C] carbon and [³H] tritium. While [¹²⁵I] iodine, [¹³³Xe] xenon, [⁵⁷Co] cobalt, [⁹⁹mTe] technetium, [¹²³I] iodine and [⁶⁷Ga] gallium, emit gamma (γ) 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 meters in air. Phosphorous is therefore known as a "hard" emitter of beta radiation, while tritium, sulfur 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.
