The GCA-07W can detect alpha, beta, x-ray and gamma radiation. Checking fish or food for radioactive contamination is a little difficult and Geiger counters, (from us or any other manufacturer) is not the ideal instrument to do so, here's why. The GCA-07W Geiger counter can detect alpha radiation. However if the fish (or food) being tested has a alpha radiation emitter internally, the food itself will block the alpha radiation and stop it from being detected. If the alpha radiation contamination is on the surface of the fish (unlikely), it can be detected. Similarly, if the fish has a beta radiation contamination internally, let's say a SR-90 contamination, the water in the flesh of the fish will effectively block the beta radiation from being detected. Again if the beta contamination is on the surface of the fish (unlikely), it can be detected. With gamma radiation the situation changes. Gamma radiation can penetrate the flesh of the fish to be detected. The problem arises is that low level contamination gamma radiation from let's say a CS-137 contamination will be indistinguishable from normal background radiation. So to test for this contamination , one method a laboratory may perform is a gamma spectroscopy (scintillation detector) to determine the source of the radiation. In the case of testing for alpha and beta radiation mentioned before, a lab might incinerate the food or fish in question down to ash. Without the water blocking radiation it becomes easier to test the material for beta and alpha contamination.On the Images website we have a number of nuclear experiments and articles. We have an article on testing food for radioactive contamination that goes into greater detail than I can here.I hope this information helps. **Q: Will this measure radon in your house?** A: The GCA-07W is sensitive to alpha radiation given off by radon. However this is not the instrument to use to detect or measure Radon in the home. There are specialty instruments and equipment available for just this purpose. **Q: Does it have an end sensitive wand?** A: I'm not sure what you mean here. The wand has an open end that exposes the mica window of the GM tube for the detection of alpha particles. In the photograph the wand has a plastic end cap on it that I recommend you keep on unless you are specifically trying to detect alpha particles. The mica window of the GM tube is thin and easily damaged. **Q: Does this unit beep or click? I have seen mixed info. Could someone upload a video of it?** A: That's an interesting question. The audio output is a tone generator. But that audio output is pulsed quickly so the tone sounds more like a click than a beep. Technically, they're both right. ## Frequently Bought Together - Geiger Counter - Digital - Professional - Model # GCA-07W External Wand Probe - ANSI N323A Certification Ready- 0.001 mR/hr Resolution - 1000 mR/hr Range - Nature's Fusions Potassium Iodide Tablets 130 mg (Pack of 2) - (120 Tablets) EXP 10/2032 - Ki Pills - Yoduro de potasio --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/6272162-geiger-counter-digital-professional-model-gca-07w-external-wand-probe](https://www.desertcart.pe/products/6272162-geiger-counter-digital-professional-model-gca-07w-external-wand-probe) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-06*
